msm: hotplug: Terminate load thresh table
msm: hotplug: Consider projected load after cpu offlined

Don't offline a cpu if we would drop under the lower
level's up threshold load. Also, add an optional hard
threshold load under which a cpu is never offlined.
Both is especially important for very short forced
online intervals.
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.
