timestamp,amd/common/apob_cache: Add timestamps for APOB
Updating the APOB takes a considerable amount of time. I decided to be
granular and split out the operations so we know when we read vs read +
erase + write.
BUG=b:179092979
TEST=Boot guybrush and dump timestamps
3:after RAM initialization 3,025,425 (44)
920:starting APOB read 3,025,430 (5)
921:starting APOB erase 3,025,478 (48)
922:starting APOB write 3,027,727 (2,249)
923:finished APOB 3,210,965 (183,238)
4:end of romstage 3,210,971 (6)
