Cpufreq: interactive: remove duplicate min_sample_time
All of the global gov tunables are moved to "tunables" structure.
"DEFAULT_MIN_SAMPLE_TIME" is reinitialized wrongly, causing
"min_sample_time" set as very high value(80ms).
This causes cpu to take more time to ramp down freq.
It removes global "min_sample_time" and sets "min_sample_time"
as 30ms to improve ramping down period.
