[Mesa-dev] [PATCH 3/3] st/va: return surface formats depending on config chroma format

[Mark Thompson]

Also allows NV12 to be returned as a supported format for video
processing.
---
The useful change is that we can now see that NV12 is supported by the video 
processor, so things like decode-scale-encode are known to be possible.

Again, there might be more supported things here which could be added.
