This adds QC10C compressed pixel format in the Venus driver, and
make it enumeratable from v4l2 clients.

Note: The QC10C format shouldn't be possible to enumerate by the
client if the decoded bitstream is not 10bits. This is not
implemented in this patch yet.

enumeratable -> possible to discover

(or possibly 'enumerable', but I prefer the phrase suggested above)

10bits -> 10-bits

Obvious question: will this be done in a later patch that is being
prepared? Would it be better to wait until such a patch is available?

Regards,
