Subject: [PATCH v5 0/2] media: HEVC: RPS clean up

This series aims to clean up Reference Picture Set usage and flags.

Long term flag was named with RPS prefix while it is not used for RPS
but for mark long term references in DBP. Remane it and remove the two
other useless RPS flags.

Clarify documentation about RPS lists content and make sure that Hantro
driver use them correctly (i.e without look up in DBP).

version 5:
- rework commit message as suggested by Ezequiel
- improve V4L2_HEVC_DPB_ENTRY_LONG_TERM_REFERENCE documentation
  with reference to HEVC ITU spec.
- add review-by tags from Jernej and Ezequiel

version 4:
- check flags with & and not ==
- remove the 2 last patches which becomes useless since VPU ctrl-blk
  driver introduction.

version 3:
- rebased on top of v5.16-rc1

version 2:
- change DPB field name from rps to flags
