Pin max and min frequencies on machine before running experiment.

Find out what is the highest static frequency (turbo mode is
considered a dynamic frequency) and set the min and max frequency
to the highest static. This reduces benchmark noise in particular
for some machines like daisy and lumpy i5.

BUG=None
TEST=Tested with runs of perf_v2. Verified frequencies are pinned.
