va: caps: add raw caps image formats with same chroma of surfaces

Browse source 
Instead of adding a list of ad-hoc formats for raw caps (I420 and
YV12), the display queries the available image formats and we assume
that driver can download frames in that available format with same
chroma of the config surfaces chroma.
