[PATCH v2] media: hantro: Be more accurate on pixel formats step_width constraints

On Hantro G2 decoder on IMX8MQ strides requirements aren't the same
for NV12_4L4 and NV12 pixel formats. The first one use a 4 bytes padding
while the last one needs 8 bytes.
To be sure to provide the correct stride in all cases we need:
- to relax the constraints on codec formats so set step_width to 4
- use capture queue format and not the output queue format when applying
the pixel format constraints.
- put the correct step_width constraints on each pixel format.
Move HEVC SPS validation in hantro_hevc.c to be able to perform it
when setting sps control and when starting to decode the bitstream.
Add a new test in HEVC SPS validation function to check if resolution
is still matching the hardware constraints.
With this SAODBLK_A_MainConcept_4 and SAODBLK_B_MainConcept_4 conformance
tests files are correctly decoded with both NV12 and NV12_4L4 pixel formats.
These two files have a resolution of 1016x760.
If step_width = 16 for the both pixel formats the selected capture
resolution is 1024x768 which is wrong for NV12_4L4 (which expect 1016x760)
on Hantro G2 on IMX8MQ (but correct for NV12).
For other variants than Hantro G2 on IMX8M keep the same step_width to avoid
regressions.
Fluster HEVC test score is now 128/147 vs 126/147 with the both pixel
formats as decoder output.
Fluster VP9 test score stay at 147/303.

version 2:
- Add a HEVC SPS validation function to be used when
setting the control and start decoding.
I hope that is what Nicolas expects in his remark on v1.
