nfit: fix format interface code byte order
Per JEDEC Annex L Release 3 the SPD data is: Bits 9~5 00 000 = Function Undefined 00 001 = Byte addressable energy backed 00 010 = Block addressed 00 011 = Byte addressable, no energy backed All other codes reserved Bits 4~0 0 0000 = Proprietary interface 0 0001 = Standard interface 1 All other codes reserved; see Definitions of Functions ...and per the ACPI 6.1 spec: byte0: Bits 4~0 (0 or 1) byte1: Bits 9~5 (1, 2, or 3) ...so a format interface code displayed as 0x301 should be stored in the nfit as (0x1, 0x3), little-endian.
