tools/power turbostat: Fix Bzy_MHz documentation typo 



The code calculates Bzy_MHz by multiplying TSC_delta * APERF_delta/MPERF_delta
The man page erroneously showed that TSC_delta was divided.

Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval

Bzy_MHz = TSC_delta*APERF_delta/MPERF_delta/measurement_interval



Note that these calculations depend on TSC_delta, so they

are not reliable during intervals when TSC_MHz is not running at the base frequency.
