cpufreq: governor: Set MIN_LATENCY_MULTIPLIER to 20
Currently MIN_LATENCY_MULTIPLIER is set defined as 100 and so on a system with transition latency of 1 ms, the minimum sampling time comes to be around 100 ms. That is quite big if you want to get better performance for your system. Redefine MIN_LATENCY_MULTIPLIER to 20 so that we can support 20ms sampling rate for such platforms.
