Aaron Durbin 24079323d4 soc/amd/stoneyridge: provide alternate monotonic timer
The TSC has been observed to be ticking at a non-constant rate
in early boot. The root cause is still not known, but this
misbehavior necessitates an alternative monotonic timer source.
Use the perf TSC which ticks at 100 MHz. This also means the
timestamp table is not accurate as well. Root cause of TSC rate
instability needs to be resolved in order to fix that.
