util: Add amdfwread utility

Amdfwtool creates AMD firmware images however there is currently no way
to get information from an existing image. This commit adds amdfwread to
support that functionality. At the moment only reading PSP soft fuse
flags is supported.

BUG=b:202397678
TEST=Ran amdfwread and verified that it correctly read the soft fuse
bits
