soc/amd/picasso: add monotonic_timer
On Zork(picasso) platform we run verstage on the PSP. It has its own
timer, but the frequency is not matched with TSC.
To ease the work to merge timestamps from the PSP and TSC, add a layer
around tsc to have microsecond granularity for timestamp table. PSP
already records timestamp in microseconds.
BUG=b:159220781
BRANCH=zork
TEST=build, flash and boot, check timestamps are correct
