I tested this, and confirmed that it's automatically preferring the tsc
timecounter.hadware. I waited a hour or two and it seems fine, and also
ran regress/sys/kern/clock_gettime with no issues reported.
As mentioned seperately, I'm not able to test suspend/resume as it is
not currently working on this machine.
