Unlike Cx/Px states, for which we need an extra loop to summerize residency (
sum_cx[]/sum_px[]), we could call get_avgfreq_by_cpuid() right before printing.
Also, with introduction of CPPC mode, average frequency print shall
not depend on the existence of legacy P-states, so we remove "px_cap"
dependancy check.
Fixes: add6160d7 (Add cpufreq actual average freq information to xenpm tools)
