Increase quality of TSC (or TSC-low) timecounter to 1000 if it is P-state
invariant. For SMP case (TSC-low), it also has to pass SMP synchronization
test and the CPU vendor/model has to be white-listed explicitly. Currently,
all Intel CPUs and single-socket AMD Family 15h processors are listed here.
