Commit 90c0ae5009 changed how the frame_type of a decoded frame
gets determined, by switching from the get_dec_frame_type to
get_disp_frame_type operation. Unfortunately it seems that on MFC v5 the
result of get_disp_frame_type is always 0 (no display) when decoding
(tested with H264), resulting in no frame ever being output from the
decoder.
This patch reverts MFC v5 to the previous behaviour while keeping the
new behaviour for v6 and up.

The following error: "error: incompatible types in conditional expression
(different base types)" was reported multiple times for the s5p-mfc
driver. This error was caused by two macro definitions - s5p_mfc_hw_call
(in s5p_mfc_common.h) and WRITEL (in s5p_mfc_opr_v6.c).
In the former case the macro assumed that all ops return a value, but some
ops return void. The solution to this problem was the addition of a
s5p_mfc_hw_call_void macro.
In the latter case the macro used the ?: construction to check whether
the address is non zero. This is not necessary after the driver left the
development and debugging cycle, so the READL and WRITEL macros were
removed.

fc906b6d "Remove special clock usage in driver" removed
initialization of MFC special clock, arguing that there's
no need to do it explicitly, since it's one of MFC gate clock's
dependencies and gets enabled along with it. However, there's
no promise of keeping this hierarchy across Exynos SoC
releases, therefore this approach fails to provide a stable,
portable solution.
Out of all MFC versions, only v6 doesn't use special clock at all.
For other versions log a message only in case clk_get fails,
as not all the devices with the same MFC version require
initializing the clock explicitly.

This patch is needed in preparation to add MFC V8
where the register offsets are changed w.r.t MFC V6/V7.
This patch adds variants of MFC V6 and V7 while
accessing MFC registers. Registers are kept in mfc context
and are initialized to a particular MFC variant during probe,
which is used instead of macros.
This avoids duplication of the code for MFC variants
V6 & V7, and reduces the if_else checks while accessing
registers of different MFC variants.

Currently, for formats that are not H264, MFC driver will check
the consumed stream size returned by the firmware and, based on that,
will try to decide whether the bitstream buffer contained more than
one frame. If the size of the buffer is larger than the consumed
stream, it assumes that there are more frames in the buffer and that the
buffer should be resubmitted for decode. This rarely works though and
actually introduces problems, because:
- v7 firmware will always return consumed stream size equal to whatever
the driver passed to it when running decode (which is the size of the whole
buffer), which means we will never try to resubmit, because the firmware
will always tell us that it consumed all the data we passed to it;
- v6 firmware will return the number of consumed bytes, but will not
include the padding ("stuffing") bytes that are allowed after the frame
in VP8. Since there is no way of figuring out how many of those bytes
follow the frame without getting the frame size from IVF headers (or
somewhere else, but not from the stream itself), the driver tries to guess that
padding size is not larger than 4 bytes, which is not always true;
The only way to make it work is to queue only one frame per buffer from
userspace and the check in the kernel is useless and wrong for VP8.
So adding VP8 also along with H264 to disallow re-submitting of buffer
back to hardware for decode.

Currently, we allocate private codec buffers on STREAMON, which may fail
if we are out of memory. We don't check for failure though, which will
make us crash with the codec accessing random memory.
We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to
allocation and deallocation of private codec buffers.

- Honor return values from vb2_reqbufs on REQBUFS(0).
- Do not set the number of allocated buffers to 0 if userspace tries
to request buffers again without freeing them.
- There is no need to verify correct instance state on reqbufs, as we will
verify this in queue_setup().
- There is also no need to verify that vb2_reqbufs() was able to allocate enough
buffers (pb_count) and call buf_init on that many buffers (i.e. dst_buf_count
is at least pb_count), because this will be verified by second queue_setup()
call as well and vb2_reqbufs() will fail otherwise.
- Only verify state is MFCINST_INIT when allocating, not when freeing.
- Refactor and simplify code.

Timestamps for destination buffers are assigned by copying them from
corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on "display status". Display status reflects the status
of the destination buffer, not source.
This used to work for firmwares version <= 6, because in addition to the above,
we'd check the decoded frame type register, which was set to "skipped" if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware >=7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).
To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. "decode status". The decode status register
values are confusing, because in its case "display" means "a frame has been
outputted to a destination buffer". We should copy if "decode and display"
is returned in it. This also works on <= v6 firmware, which behaves in the same
way with regards to decode status register.

The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.
The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.
The pwc amd sdr-msi3101 drivers both had this construction:
if (mutex_lock_interruptible(&s->v4l2_lock))
return -ERESTARTSYS;
This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

s5p_mfc_get_node_type() relies on get_index() helper function, which in
turn relies on video_device index numbers assigned on driver
registration. All this code is not really needed, because there is
already access to respective video_device structures via common
s5p_mfc_dev structure. This fixes the issues introduced by patch
1056e4388b ("v4l2-dev: Fix race condition
on __video_register_device"), which has been merged in v3.12-rc1.
