allow vaDeriveImage() to work for UYVY formats
allow vaDeriveImage() to work for UYVY formats

Hi,

I would push the following as obvious around next week.

Add support for UYVY format to vaDeriveImage(). Also remove dead code
along the way, i.e. packed YUV 4:2:2 formats have a single plane.

Regards,
Gwenole.
