perf/x86/intel/pt: Export CPU frequency ratios needed by PT decoders
Intel PT decoders need access to various bits of timing related
information to be able to correctly decode timing packets from a PT
stream (MTC and CBR packets). This patch exports all the necessary
bits as sysfs attributes for the sake of consistency:
* max_nonturbo_ratio: ratio between the invariant TSC and base clock;
* tsc_art_ratio: TSC to core crystal clock ratio (also available as CPUID.15H).
