cpufreq: change min_sample_time
We prefer a min_sample_time of 30ms. This is tied to our cluster switch
and auto-hotplug artificial delays.

original commit message:
cpufreq: reduce min_sample_time
Reduce the minimum amount of time the interactive governor spends at a
frequency before ramping down. This parameter (min_sample_time) was 80ms
now reduced to 30 ms based on perf and power sweep numbers.
