Hi all,

This patch set implements region of interest(ROI) support for
video encoder to be configured as a MB based delta_qp for
the whole frame. Custom controls V4L2_CID_MPEG_VIDEO_ROI_MB_DELTA_QP
and V4L2_CID_MPEG_VIDEO_ROI_MB_SIZE are implemented to achieve this.
Corresponding support is added in iris encoder to implement this
feature.

This submission and design is based on the feedback received
from community for the RFC[1] series posted earlier.
Initial testing is done by adding support to v4l2-ctl[2] to test this
control setting and its functionality.
