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
