amdfwtool: Add support for AMD's BIOS A/B recovery feature
The rom layout for A/B recovery:
EFS -> PSP L1 0x48 -> PSP L2 A -> BIOS L2 A
0x4A -> PSP L2 B -> BIOS L2 B
The coreboot doesn't implement the AMD's A/B recovery. This is only
for the ROM layout. To save some flash space, the entire B section can
be eliminated.
To enable A/B recovery in PSP layout, add "--recovery-ab" to
amdfwtool.
