[v3,1/3] media: v4l2-ctrl: Add frame-specific min/max qp controls for hevc
Commit Message
- Adds min/max qp controls for B frame for h264.
- Adds min/max qp controls for I/P/B frames for hevc similar to h264.
- Update valid range of mim/max qp for hevc to accommodate 10 bit.

Hi Dikshita,
Just a few nitpicks, I'd have changed it myself, but since a new version is
needed anyway you might as well change it for next time :-)
