[PATCH] dt-bindings: interrupt-controller: Convert aspeed,ast2xxx-scu-ic to DT schema

[Rob Herring (Arm)]

Convert the Aspeed SCU interrupt controller binding to schema format.
It's a straight-forward conversion of the typical interrupt controller.

-Aspeed AST25XX and AST26XX SCU Interrupt Controller
-
-Required Properties:
- - #interrupt-cells		: must be 1
- - compatible			: must be "aspeed,ast2500-scu-ic",
-				  "aspeed,ast2600-scu-ic0" or
-				  "aspeed,ast2600-scu-ic1"
- - interrupts			: interrupt from the parent controller
- - interrupt-controller		: indicates that the controller receives and
-				  fires new interrupts for child busses
-
-Example:
-
-    syscon at 1e6e2000 {
-        ranges = <0 0x1e6e2000 0x1a8>;
-
-        scu_ic: interrupt-controller at 18 {
