amdfwtool: Add ISH header support for A/B recovery layout
Image Slot Header (ISH) is a new feature.
The rom layout for A/B recovery with ISH:
EFS -> PSP L1 0x48 -> ISH A -> PSP L2 A -> BIOS L2 A
0x4A -> ISH B -> PSP L2 B -> BIOS L2 B
The newer 55758 will updated about the boot priority and update retry
in ISH header.
