[PATCH v2 17/23] 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.

+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>;
