dt-bindings: thermal: Convert marvell,armada370-thermal to DT schema

Convert the Marvell Armada 3xx/XP thermal binding to schema.

Drop the AP80x and CP110 as they have long been deprecated and have
been replaced by a new binding.

-* Marvell Armada 370/375/380/XP thermal management
-
-Required properties:
-
-- compatible: Should be set to one of the following:
-    * marvell,armada370-thermal
-    * marvell,armada375-thermal
-    * marvell,armada380-thermal
-    * marvell,armadaxp-thermal
-    * marvell,armada-ap806-thermal
-    * marvell,armada-ap807-thermal
-    * marvell,armada-cp110-thermal
-
-Note: these bindings are deprecated for AP806/CP110 and should instead
-follow the rules described in:
-Documentation/devicetree/bindings/arm/marvell/ap80x-system-controller.txt
-Documentation/devicetree/bindings/arm/marvell/cp110-system-controller.txt
-
-- reg: Device's register space.
-  Two entries are expected, see the examples below. The first one points
-  to the status register (4B). The second one points to the control
-  registers (8B).
-  Note: The compatibles marvell,armada370-thermal,
-  marvell,armada380-thermal, and marvell,armadaxp-thermal must point to
-  "control MSB/control 1", with size of 4 (deprecated binding), or point
-  to "control LSB/control 0" with size of 8 (current binding). All other
-  compatibles must point to "control LSB/control 0" with size of 8.
-
-Examples:
-
-	/* Legacy bindings */
-	thermal@d0018300 {
-		compatible = "marvell,armada370-thermal";
-		reg = <0xd0018300 0x4
-		       0xd0018304 0x4>;
-	};
-
-	ap_thermal: thermal@6f8084 {
-		compatible = "marvell,armada-ap806-thermal";
-		reg = <0x6f808C 0x4>,
-		      <0x6f8084 0x8>;
