media: venus: Add a handling of QC10C compressed format

Browse Source 
This adds QC10C compressed pixel format in the Venus driver, and
make it possible to discover from v4l2 clients.

Note: The QC10C format will be enumerable via VIDIOC_ENUM_FMT when
the bitstream is 10-bits and the headers are parsed.
