Michał Żygowski bf148cae0a lib/dimm_info_util.c: Handle 16-bit memory bus extension for ECC 
Some silicon initialization modules, like OpenSIL report bus width
extension as 16 bits for ECC for DDR5 memories. Handle this case
correctly for DDR5 and LPDDR5 memories by reporting appropriate
bitfield of the SPD width. This field is used later by coreboot to
calculate the bus extension again, which results in 16bit extension
for ECC.
