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. Example usage: `amdfwread --soft-fuse bios.bin`,
example output: `Soft-fuse:0x400000030000041`.
BUG=b:202397678
TEST=Ran amdfwread and verified that it correctly reads the soft fuse
bits, verified that built AMD FW still boots on DUT
