msm: hotplug: Refactor load calculation

* Move core load calculations to this file and optimize.
* Calculate load based on current policy->max, not cpuinfo.max_freq
  which explains the strange 78% maximum load value before.
* Recalculate thresholds and fast_lane_load accordingly.
* Cleanup some ambiguous namings and other minor stuff.
* EXPORT_SYMBOL_* is useless for static functions.

[ neo:
* Adapt to our changes.
* Use myfluxi's LOAD_BALANCE values which seems conservative but worth a try.
* Do not merge LCD Notifier.
* Leftover cleanup.
* Do not disable RQ_STATS as we need same for Alucard Hotplug for now. ]
