[v9,0/6] media: verisilicon: HEVC: fix 10bits handling

  When decoding a 10bits bitstreams HEVC driver should only expose 10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
and to only change driver internal state in case of success.

Fluster score for HEVC (140/147) doesn't change after this series.
Fluster score for VP9 is 146/303.
Fluster score for VP8 is 59/61.
Fluster score for H.264 is 129/135.

version 9:
- Fix brackets
- Remove Fixes tags
- Run fluster for VP8, H264.
- Add compliance tests results.
- Rebased on v6.2-rc7
- My hardware doesn't support JPEG encoder so I can't test it.

version 8:
- Correct patch 4.
- Add a patch for VP9.

version 7:
- Remove unused ctx variable in hantro_try_ctrl().
- Change HANTRO_DEFAULT_BIT_DEPTH value to 8.
- Simplify hantro_check_depth_match logic.
- Keep ctx->bit_depth as integer value because it is use
  to compute buffers size for hevc.

version 6:
- Split the patches in multiple sub-patches.
- Rework hantro_reset_encoded_fmt() usage.

version 5:
- Add Nicolas's review tags
- Add Fixes tags

version 4:
- Split the change in 2 patches.
- Change hantro_check_depth_match() prototype to avoid using
  ctx->bit_depth
- Return the result of hantro_reset_raw_fmt() to the caller.
- Only set ctx->bit_depth when hantro_reset_raw_fmt() returns is ok.
 
Benjamin Gaignard (6):
  media: verisilicon: Do not set context src/dst formats in reset
    functions
  media: verisilicon: Do not use ctx fields as format storage when
    resetting
  media: verisilicon: Do not set ctx->bit_depth in hantro_try_ctrl()
  media: verisilicon: Do not change context bit depth before validating
    the format
  media: verisilicon: HEVC: Only propose 10 bits compatible pixels
    formats
  media: verisilicon: VP9: Only propose 10 bits compatible pixels
    formats
