Subject: [RFC] media: uapi: Move HEVC stateless controls out of staging
The HEVC stateless 'uAPI' was staging and marked explicitly in the
V4L2 specification that it will change and is unstable.
Note that these control IDs were never exported as a public API,
they were only defined in kernel-local headers (hevc-ctrls.h).
While moving the controls out of staging they are renamed and
control IDs get new numbers.
Drivers (Hantro, Cedrus) and Documentation are updated accordaly.
Additional structures fields has been added for RKVDEC driver usage.
Hantro dedicated control is moving to hantro-media.h
Since hevc-ctrls.h content has been dispatched in others file, remove it.
fluster tests results on IMX8MQ is 77/147 for HEVC codec.
