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

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

Please note that the only purpose of commits 3 and 4 is to allow to test
G2 hardware block for IMX8MQ until a proper solution isuing power domain
can be found. Do not merge them.

GStreamer HEVC plugin merge request can be found here:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1079

With those piece of code fluster score is 77/147.
