This series aims to make HEVC uapi stable and usable for hardware
decoder. HEVC uapi is used by 2 mainlined drivers (Cedrus and Hantro)
and 2 out of the tree drivers (rkvdec and RPI).

After the remarks done on version 2, I have completely reworked to patches
split so changelogs are meaningless. I have also drop "RFC" from the
titles.

Version 4:
- Add num_entry_point_offsets field in struct v4l2_ctrl_hevc_slice_params
- Fix V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS name
- Initialize control V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS
- Fix space/tab issue in kernel-doc
- Add patch to change data_bit_offset definition
- Fix hantro-media SPDX license
- put controls under stateless section in v4l2-ctrls-defs.c

At the end fluster tests results on IMX8MQ is 77/147 for HEVC codec.
