Subject: cpufreq: fix ondemand governor powersave_bias execution time misuse
From: Youquan Song <youquan.song@linux.intel.com>

Ondemand governor use powersave_bias tunable to do aggressive power save
by decrease CPU average frequency.  The average frequency achieve by
adjust low and high frequency's execution time proportion during one
sample time interval.

Current kernel, only the high frequency executes in time proportion, but
the low frequency wrongly execute in one whole sample time interval when
powersave_bias is set.

The patch fix it by set low frequency execution time to it deserved.
