tools/power/turbostat: Abstract BCLK frequency support
Abstract CPU base clock frequency support.
Note that bclk is used by
1. calculate base_hz using MSR_PLATFORM_INFO, which is guarded by
probe_nhm_msrs().
2. dump MSR_PLATFORM_INFO and Turbo Ratio Limit MSRs, which are also
guarded by probe_nhm_msrs().
Thus probe_bclk() works for probe_nhm_msrs() models only.
