[Mesa-dev] [PATCH 07/12] st/va: add conversion for yv12 to nv12in putimage

[Boyuan Zhang]

For putimage call, if image format is yv12 (or IYUV with U V field swap) and 
surface format is nv12, then we need to convert yv12 to nv12 and then copy the 
converted data from image to surface. We can't use the existing logic where 
surface is destroyed and re-created with yv12 format.
