[Mesa-dev] [PATCH 7/9] st/va: add support for P010 and P016 formats v2

[Christian König]

From: Christian König <christian.koenig at amd.com>

No hardware I know off can actually support P010 natively. But we can easily
support P016 and as long as nobody decodes anything into the lower 6bits it
doesn't make any difference to P010.

v2: allow P0160 for post processing as well
