x86/cpufreq: Rework APERF/MPERF handling

Currently, each feature_detect() (called on CPU add) hook for both cpufreq
drivers duplicates cpu_has_aperfmperf in a per-cpu datastructure, and edits
cpufreq_driver.getavg to point at get_measured_perf().

As all parts of this are vendor-neutral, drop the function pointer and
duplicated boolean, and call get_measured_perf() directly.
