From: Maxime Ripard <maxime.ripard@bootlin.com>

The Allwinner SoCs have an interrupt controller supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

Changes from v1:
  - Remove Fixme and add additionalProperties to false
  - Add unit address for the example

-Required properties:
-
-- compatible : should be one of the following:
-              "allwinner,sun4i-a10-ic"
-              "allwinner,suniv-f1c100s-ic"
-- reg : Specifies base physical address and size of the registers.
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source. The value shall be 1.
-
-Example:
-
-intc: interrupt-controller {
-	compatible = "allwinner,sun4i-a10-ic";
-	reg = <0x01c20400 0x400>;
-	interrupt-controller;
