power: cpufreq interactive governor: use default sample time 20ms

Lower the default time at which a higher speed is allowed to run
before lowering based on lower CPU load from 80ms to 20ms.  Most
Android devices should trade power for performance here,
although tablets and non-battery-powered devices may want to
override this default.
