Subject: [PATCH 3/3] venus: Add a handling of QC10C compressed format
Date:   Thu, 29 Apr 2021 13:58:15 +0300

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.
