Cpufreq S3 suspend/resume logic

Based on cpufreq init logic reconstruct,
this patch implement cpufreq S3 suspend/resume logic.
When suspend to S3, it stop cpufreq dbs governor;
When resume from S3, firstly it sync cpu state and freq
at the 1st dbs timer; from 2nd dbs timer on, cpufreq
dbs governor control cpu px transfer according to
its workload algorithm.
Px statistic is also handled S3 suspend/reusme accordingly.
