intelli/msm_thermal: initial coding for Qualcomm S4 Pro devices (thx faux)

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.
