util/amdfwtool/amdfwread: Fix AMDFW_OPT* bit mask 

Optional arguments that involve printing information from the firmware
image is mapped to bit fields with bit 31 set. But instead of just
setting bit 31, bits 27 - 31 are set. Fix AMDFW_OPT* bit mask.

BUG=None
TEST=Build and use amdfwread to read the Soft-fuse bits from Guybrush
BIOS image. Observed no changes before and after the changes.
