Revert dubious scheduler changes.

 * Rolled this series back on other devices as well. It's causing bad

Change-Id: I7fcb7b2a7bb5657bf70a2189b2d04a5289987106
cpufreq: interactive: Honor changed minimum frequency

This saves a few cycles in the timer routine.
cpufreq: interactive: Use parts of native boost routine

Not all governors are created equal. Set boostpulse_endtime
and floor_freq to smoothen the timer routine.
cpufreq: interactive: Use frequency dependent per cpu timings

This allows in-depth testing of the timer routine.
cpufreq: interactive: Honor boosted state when entering idle

The old logic didn't take the boosted state in account. Just
leave the comment intact because our temporary min is not
the regular policy->min it refers to.
msm: hotplug: Optimize latencies

Before this patch it took the algorithm too long to
react on sudden load spikes, although only noticable
in benchmarks. We would cycle 5-6 times until the
buffer average was finally high enough to trigger a
new target.  Improve latencies by instantly onlining
all cpus if current load on any cpu is above a certain
threshold.

fast_lane_load should not be higher than 78 as load
per cpu won't be above this value in our metric.
