G2/HEVC is added inside the already exiting Hantro driver, it is "just"
an other codec from Hantro driver point of view.
In addition of that v4l2-hevc uAPI is still unstable.
One goal of this series is to have one more consumer of this v4l2-hevc
uAPI so maybe we can claim it to be stable enough to move away from staging
and then do the same for Hantro driver. That would be a great achievement !
