dt-binding: thermal: Convert marvell,armada-ap806-thermal to DT schema

Browse Source 
Convert the Marvell Armada AP80x/CP110 thermal binding to schema. It is
a straight forward conversion.

===================
Thermal:
--------
For common binding part and usage, refer to
Documentation/devicetree/bindings/thermal/thermal*.yaml
The thermal IP can probe the temperature all around the processor. It
may feature several channels, each of them wired to one sensor.
It is possible to setup an overheat interrupt by giving at least one
critical point to any subnode of the thermal-zone node.
Required properties:
- compatible: must be one of:
* marvell,armada-ap806-thermal
- reg: register range associated with the thermal functions.
Optional properties:
- interrupts: overheat interrupt handle. Should point to line 18 of the
SEI irqchip. See interrupt-controller/interrupts.txt
- #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>;
interrupt-parent = <&sei>;
interrupts = <18>;
#thermal-sensor-cells = <1>;
};

- reg: register range associated with the thermal functions.
Optional properties:
- interrupts-extended: overheat interrupt handle. Should point to
a line of the ICU-SEI irqchip (116 is what is usually used by the
firmware). The ICU-SEI will redirect towards interrupt line #37 of the
AP SEI which is shared across all CPs.
See interrupt-controller/interrupts.txt
- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
