va: allocator: try to create surface without fourcc but chroma only

Browse source 
There are, in VPP, surfaces that doesn't support 4:2:2 fourccs but it
supports the chroma. So this patch gives that opportunity to the
driver.

This patch also simplifiies
gst_va_video_surface_format_from_image_format() to just an iterator
for surfaces available formats.
