util/amdfwtool: Clarify calculations with structures

Replace the use of multiples of DWORDs with structures that
describe the Embedded Firmware Table, and PSP directory
headers & entries.

TEST=Verify no difference in amdfw.rom for google/grunt build
     (Family 15h Models 70h-7Fh), amd/bettong (F15h 60h-6Fh),
     and pcengines/apu2 (F16h 30h-3Fh).  PSP_COMBO builds but
     was not verified.
