dt-bindings: ap806: 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.

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

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



Required properties:

- compatible: must be one of:

  * marvell,armada-ap806-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, while positive

  IDs refer to each CPU.



Example:

ap_syscon1: system-controller@6f8000 {

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

	reg = <0x6f8000 0x1000>;



	ap_thermal: thermal-sensor@80 {

		compatible = "marvell,armada-ap806-thermal";

		reg = <0x80 0x10>;

		#thermal-sensor-cells = <1>;

	};

};
