SF: Hash and cache descriptor block serial number
More EDID fields are required as a part of migrating to EDID-based
display IDs. This CL parses the device's serial number from the serial
number descriptor bloc, (depicted by the FF marker), hashes it using a
stable hash, and serves it as a part of the Edid struct.
Later, amongst others, this value will be used to fabricate a unique
display ID that is based on the display's EDID.
