[PATCH] tools/power turbostat: Fix Bzy_MHz calculation equation

[Peng Liu]

From: Peng Liu <liupeng17@xxxxxxxxxx>

To calculate Bzy_MHz, TSC_delta should multiply APERF_delta instead
of dividing it.

 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.
