crosperf: Setup CPU frequency
Added "cpu_freq_pct" in global settings specifying percent of the max
frequency which will be set on DUT during benchmark run. The actual
value will be chosen from available frequencies less than or equal to
the calculated number.
Feature requires scaling_available_frequencies. On the platforms not
supporting scaling_available_frequencies "cpu_freq_pct" will be ignored.
BUG=chromium:966514
TEST=Unittest and local HW tests on veyron, scarlet and kevin64 passed.
