The mmp ccic driver expects a platform_data structure that does not exist

leads to build errors now:

Add media controller support to the adv7180 driver by registering a media
entity instance for it as well as implementing pad ops for configuring the
format.
As there currently don't seem to be any users of the video ops format
operations those are removed as well in this patch.
Also set the V4L2_SUBDEV_FL_HAS_DEVNODE flag for the subdevice so it is
possible to create a subdevice device node.
Since the driver now depends on VIDEO_V4L2_SUBDEV_API all drivers which
select the driver need to depend on that symbol as well.

The davinci media drivers use videobuf2, which they enable through
a 'select' statement. If one of these drivers is built-in, but
the v4l2 core is a loadable modules, we end up with a link
error:
drivers/built-in.o: In function `vb2_fop_mmap':
:(.text+0x113e84): undefined reference to `video_devdata'
drivers/built-in.o: In function `vb2_ioctl_create_bufs':

drivers/built-in.o: In function `vb2_ioctl_reqbufs':

drivers/built-in.o: In function `vb2_ioctl_querybuf':
:(.text+0x115530): undefined reference to `video_devdata'
To solve this, we need to add a dependency on VIDEO_V4L2,
which enforces that the davinci drivers themselves can only
be loadable modules if V4L2 is not built-in, and they do
not cause the videobuf2 code to be built-in.

The timberdale media driver requires the use of the respective
dma engine driver, but that may not be enabled, causing a
Kconfig warning:
warning: (VIDEO_TIMBERDALE) selects TIMB_DMA which has unmet direct dependencies (DMADEVICES && MFD_TIMBERDALE)
This fixes the dependency by removing the inappropriate 'select'
statement and replacing it with a direct dependency on the
drivers that provide the services this needs.

This commit moves the "buffer in use" logic from the .buf_cleanup
handler into .stop_streaming, based on advice that this is its
proper logical home.
By ensuring the list of pointers in priv->queue_buf[] is managed
as soon as possible, we avoid warnings concerning buffers in ACTIVE
state when the system cleans up after streaming stops. This fixes a
problem with modification of buffers after their content has been
cleared for passing to userspace.
After the refactoring, the buf_init and buf_cleanup functions were
found to contain only initialisation/release steps as are carried out
elsewhere if omitted; these functions and references were removed.

The code that tests that capture from a stream has stopped is
presently insufficient and the potential for a race condition
exists where frame capture may generate an interrupt between
requesting the capture process halt and freeing buffers.
This patch refactors code out of rcar_vin_videobuf_release() and
into rcar_vin_wait_stop_streaming(), and ensures there are calls
in places where we need to know that capturing has finished.

The MFC driver has two controls, DISPLAY_DELAY and DISPLAY_DELAY_ENABLE
that allow forcing the decoder to return a decoded frame sooner
regardless of the order. The added support for firmware version 6 and
higher was not taking into account the DISPLAY_DELAY_ENABLE boolean.
Instead it had a comment stating that DISPLAY_DELAY should be set to a
negative value to disable it. This is not possible since the control
range is from 0 to 65535. This feature was also supposed to be disabled
by default in order to produce frames in display order.
