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.
