Gwenole Beauchesne 85a60441fa decoder: h264: properly support grayscale formats.
Request the correct chroma format for decoding grayscale streams.
i.e. make lookups of the VA chroma format more generic, thus possibly
supporting more formats in the future.

This means that, if a VA driver doesn't support grayscale formats,
it is now going to fail. We cannot safely assume that maybe grayscale
was implemented on top of some YUV 4:2:0 with the chroma components
all set to 0x80.
