Pull thermal management updates from Zhang Rui:

 - Add Daniel Lezcano as the reviewer of thermal framework and SoC
   driver changes (Daniel Lezcano).

 - Fix a bug in intel_dts_soc_thermal driver, which does not translate
   IO-APIC GSI (Global System Interrupt) into Linux irq number (Hans de
   Goede).

 - For device tree bindings, allow cooling devices sharing same trip
   point with same contribution value to share cooling map (Viresh
   Kumar).
