dt-bindings: thermal: Convert brcm,sr-thermal to DT schema 



Convert the brcm,sr-thermal binding to DT schema format. It's a
straight-forward conversion. "polling-delay", "thermal-sensors", and
"temperature" all apply to the thermal zones, not the sensor node.

This binding describes thermal sensors that is part of Stingray SoCs.



Required properties:

- compatible : Must be "brcm,sr-thermal"

- reg : Memory where tmon data will be available.

- brcm,tmon-mask: A one cell bit mask of valid TMON sources.

                  Each bit represents single TMON source.

- #thermal-sensor-cells : Thermal sensor phandler

- polling-delay: Max number of milliseconds to wait between polls.

- thermal-sensors: A list of thermal sensor phandles and specifier.

                   specifier value is tmon ID and it should be

                   in correspond with brcm,tmon-mask.

- temperature: trip temperature threshold in millicelsius.



Example:

	tmons {

		compatible = "simple-bus";

		#address-cells = <1>;

		#size-cells = <1>;

		ranges = <0x0 0x0 0x8f100000 0x100>;



		tmon: tmon@0 {

			compatible = "brcm,sr-thermal";

			reg = <0x0 0x40>;

			brcm,tmon-mask = <0x3f>;

			#thermal-sensor-cells = <1>;

		};

	};



	thermal-zones {

		ihost0_thermal: ihost0-thermal {

			polling-delay-passive = <0>;

			polling-delay = <1000>;

			thermal-sensors = <&tmon 0>;

			trips {

				cpu-crit {

					temperature = <105000>;

					hysteresis = <0>;

					type = "critical";

				};

			};

		};

		ihost1_thermal: ihost1-thermal {

			polling-delay-passive = <0>;

			polling-delay = <1000>;

			thermal-sensors = <&tmon 1>;

			trips {

				cpu-crit {

			trips {
