It seems that for some HEVC videos at least one bitstream parsing
trigger must be called in order to be decoded correctly. There is no
explanation why this helps, but it was observed that several videos
with this fix are now decoded correctly and there is no regression with
others.
Without this fix, those same videos totally crash HEVC decoder (other
decoder engines are unaffected). After decoding those problematic
videos, HEVC decoder always returns only green image (all zeros).
Only complete HW reset helps.
This fix is similar to that for H264.

The Hantro G1 decoder is able to enable a post-processor
on the decoding pipeline, which can be used to perform
scaling and color conversion.
The post-processor is integrated to the decoder, and it's
possible to use it in a way that is completely transparent
to the user.
This commit enables color conversion via post-processing,
which means the driver now exposes YUV packed, in addition to NV12.

+---------------------------+
| UV-plane 128 bytes x MBs |

+---------------------------+
The motion vector buffer offset is currently correct for 4:2:0 because
the extra space for motion vectors is overallocated with an extra
64 bytes x MBs.
Wrong offset for both destination and motion vector buffer are used
for the bottom field of field encoded content, wrong offset is
also used for 4:0:0 (monochrome) content.
Fix this by setting the motion vector address to the expected 384 bytes
x MBs offset for 4:2:0 and 256 bytes x MBs offset for 4:0:0 content.
Also use correct destination and motion vector buffer offset
for the bottom field of field encoded content.
While at it also extend the check for 4:0:0 (monochrome) to include an
additional check for High Profile (100).

However, and according to the mem-to-mem stateless decoder specification,

There are few variations of 4k resolutions. The biggest one is
4096x2304 which is also supported by HW. It has also nice property that
both width and size are divisible by maximum HEVC CTB size, which is 64.

Mode register also holds information if video width is bigger than 2048
and if it is equal to 4096.

The picture order count table only makes sense for profiles
higher than Baseline. This is confirmed by the H.264 specification
(See 8.2.1 Decoding process for picture order count), which
clarifies how POC are used for features not present in Baseline.
"""
Picture order counts are used to determine initial picture orderings
for reference pictures in the decoding of B slices, to represent picture
order differences between frames or fields for motion vector derivation
in temporal direct mode, for implicit mode weighted prediction in B slices,
and for decoder conformance checking.
"""
As a side note, this change matches various vendors downstream codebases,
including ChromiumOS and IMX VPU libraries.

The setting of the motion vectors usage and the setting of motion
vectors address are currently done under different conditions.
When decoding pre-recorded videos, this results of leaving the motion
vectors address unset, resulting in faulty memory accesses. Fix it
by using the same condition everywhere, which matches the profiles
that support motion vectors.

TRM specify supported image size 48x48 to 4096x2304 at step size 16 pixels,
change frmsize max_width/max_height to match TRM at [1].
This patch makes it possible to decode the 4096x2304 sample at [2].

Scaling list supplied from userspace should be in matrix order
and can be used without applying the inverse scanning process.
The HW also only support 8x8 scaling list for the Y component, indices 0
and 1 in the scaling list supplied from userspace.
Remove reordering and write the scaling matrix in an order expected by
the VPU, also only allocate memory for the two 8x8 lists supported.

It seems that for some H264 videos at least one bitstream parsing
trigger must be called in order to be decoded correctly. There is no
explanation why this helps, but it was observed that two sample videos
with this fix are now decoded correctly and there is no regression with
others.

Compliance test for imx-media-captu device /dev/video0:
Driver Info:
Driver name : imx-media-captu
Card type : imx-media-capture
...
The driver name string is limited to 16 characters, so provide
a shorter name so that we can have a better output.
While at it, use the same shorter name for driver and card.
