HDMI 2.1 redefines previously reserved fields in SCDC for various new uses. No version check needs to be performed, as an HDMI 2.0 sink's reserved SCDC fields are well-defined to be 0, and any zero-ness of these fields for an HDMI 2.0 sink is not a surprise for SCDC parsers for HDMI 2.1. Implement reading and outputting these fields over debugfs.
