soc/amd/common/block/apob: Add hashed APOB support
Comparing the APOB in RAM to flash takes a significant amount of time
(~11ms). Instead of comparing the entire APOB, use a fast hash function
and compare just that. Reading, hashing, and comparing the hash take
~70 microseconds.
BUG=b:193557430
TEST=compile and boot to OS in chausie with and without this option set
