Fix printing & reading of 16-bit CFI device identifiers
Fix reading and printing of CFI flashes 16-bit devices identifiers
Nowadays CFI flashes have a 16-bit device identifier. U-boot still
print them and read them as if they were only 8-bit wide. Fix that.
Before:
Intel Extended command set, Manufacturer ID: 0x89, Device ID: 0x1B
After:
Intel Extended command set, Manufacturer ID: 0x89, Device ID: 0x881B
