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

v2:
 - Mention the SEI connection

---------

-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>;
