dt-bindings: cp110: add the thermal node in the syscon file 



Explain the thermal bindings now that the thermal IP is described being
inside of a system controller. Add a reference to the thermal-zone node.

SYSTEM CONTROLLER 1

===================



Thermal:

--------



The thermal IP can probe the temperature all around the processor. It

may feature several channels, each of them wired to one sensor.



For common binding part and usage, refer to

Documentation/devicetree/bindings/thermal/thermal.txt



Required properties:

- compatible: must be one of:

  * marvell,armada-cp110-thermal

- reg: register range associated with the thermal functions.



Optional properties:

- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer

  to this IP and represents the channel ID. There is one sensor per

  channel. O refers to the thermal IP internal channel.



Example:

CP110_LABEL(syscon1): system-controller@6f8000 {

	compatible = "syscon", "simple-mfd";

	reg = <0x6f8000 0x1000>;



	CP110_LABEL(thermal): thermal-sensor@70 {

		compatible = "marvell,armada-cp110-thermal";

		reg = <0x70 0x10>;

		#thermal-sensor-cells = <1>;

	};

};
