Pull thermal management update from Zhang Rui:
 "Highlights:

   - Introduction of thermal policy support, together with three new
     thermal governors, including step_wise, user_space, fire_share.

   - Introduction of ST-Ericsson db8500_thermal driver and ST-Ericsson
     db8500_cpufreq_cooling driver.

   - Thermal Kconfig file and Makefile refactor.

   - Fixes for generic thermal layer, generic cpucooling, rcar thermal
     driver and Exynos thermal driver."

* ST-Ericsson DB8500 Thermal
** Thermal node properties:
- compatible : "stericsson,db8500-thermal";
- reg : address range of the thermal sensor registers;
- interrupts : interrupts generated from PRCMU;
- interrupt-names : "IRQ_HOTMON_LOW" and "IRQ_HOTMON_HIGH";
- num-trips : number of total trip points, this is required, set it 0 if none,
if greater than 0, the following properties must be defined;
- tripN-temp : temperature of trip point N, should be in ascending order;
- tripN-type : type of trip point N, should be one of "active" "passive" "hot"
"critical";
- tripN-cdev-num : number of the cooling devices which can be bound to trip
point N, this is required if trip point N is defined, set it 0 if none,
otherwise the following cooling device names must be defined;
- tripN-cdev-nameM : name of the No. M cooling device of trip point N;
Usually the num-trips and tripN-*** are separated in board related dts files.
Example:
thermal@801573c0 {
compatible = "stericsson,db8500-thermal";
reg = <0x801573c0 0x40>;
interrupts = <21 0x4>, <22 0x4>;
interrupt-names = "IRQ_HOTMON_LOW", "IRQ_HOTMON_HIGH";
num-trips = <3>;
trip0-temp = <75000>;
trip0-type = "active";
trip0-cdev-num = <1>;
trip0-cdev-name0 = "thermal-cpufreq-0";
trip1-temp = <80000>;
trip1-type = "active";
trip1-cdev-num = <2>;
trip1-cdev-name0 = "thermal-cpufreq-0";
trip1-cdev-name1 = "thermal-fan";
trip2-temp = <85000>;
trip2-type = "critical";
trip2-cdev-num = <0>;
