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.

In this v3 I do all the changes (new controls, documentation, etc..)
in the staging directory before moving the HEVC uAPI to stable 
steps by steps (unlike the big one patch in v2).

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