Add hevc stateless decoder driver to support hardware decode in MT8195, and the driver
need num_delta_pocs_of_ref_rps_idx value to parse slice header short_term_ref_pic_set().
patch 1 add num_delta_pocs_of_ref_rps_idx field.
patch 2 add hevc stateless decoder driver.
---
Changed from v6:
- fix AngeloGioacchino's suggestion.
Changed from v5:
- checkpatch/kernel-doc pass/build pass.
- fix warning: struct vdec_av1_slice_fb -> struct vdec_hevc_slice_fb.
- fix warning: remove unused comment for param "trans_start" and "trans_end"
Changed from v4:
- fix some comments according to Nathan's suggestion.
Changed from v3:
- add the dependency patch to this patch series for patch 1.
Changed from v2:
- fix one build warning.
- add the dependency patch link.
Changed from v1:
- fix build error when build 32bit system.
- hevc fluster test result: 132/147 (not support: 10bit => 11 and resolution => 4).
