intelli/msm_thermal: initial coding for Qualcomm Snapdragon 800 devices

an intelligent MSM thermal throttling kernel driver designed to replace
the closed sourced thermald(aemon) from Qualcomm.

The current driver can throttle the SOC via core frequency scaling or
via
core hotplug with user configurable sysfs entries to adjust the
throttling temperature thresholds for each.

Derived from Qualcomm's Open source repo.
