ARM: dts: msm: Add thermal properties to MSM8937 devicetree 



Add thermal properties to enable kernel thermal monitoring
and mitigations like hotplug, frequency mitigation,
thermal reset, vdd restriction etc for MSM8937.
Add mitigation profiles for each physical CPU which has information
like sensor and various mitigation types including boot frequency
mitigation, emergency hotplug mitigation and emergency frequency
mitigation for MSM8937.
