Partial backport of fc04cc67ea8f44124f048832a745a24bc2fa12fa
from Len Brown <len.brown@intel.com>

Add Avg_MHz column, which is the frequency that many
users expect to see -- the total number of cycles executed
over the measurement interval.

People found the previous GHz to be confusing, since
it was the speed only over the non-idle interval.
That measurement has been re-named Bzy_MHz.
