SF: Parse, hash, and cache block 0 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 bytes 12-15 of block 0 in the EDID blob, 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. See: 1.
