In anticipation of userspace being able to explicitly select supported sink formats, add handling of the YCBCR444 sink format. The AUTO path does not choose this format, but with explicit format selection added to the driver, it becomes a possibility.
Check for YCBCR444 support on the sink in both sink_bpc_possible, and sink_format_valid.
