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.

Looks to me like you could enable this.

BTW, I think the fix is going to be just the new
'unevaluatedProperties: false'. We could start putting that in as
unknown keys are ignored (though the meta-schema will need an update
to allow it).

unit-address needed.

I need to figure out how to enable dtc warnings by default on the examples...

-Required properties:
-
-- compatible : should be one of the following:
-              "allwinner,sun4i-a10-ic"
-              "allwinner,suniv-f1c100s-ic"

-- 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.
