dt-bindings: interrupt-controller: Convert snps,archs-intc to DT schema 

Convert the ARC-HS incore interrupt controller binding to schema format.
It's a straight-forward conversion of the typical interrupt controller.

* ARC-HS incore Interrupt Controller (Provided by cores implementing ARCv2 ISA)



Properties:



- compatible: "snps,archs-intc"

- interrupt-controller: This is an interrupt controller.

- #interrupt-cells: Must be <1>.



  Single Cell "interrupts" property of a device specifies the IRQ number

  between 16 to 256



  intc accessed via the special ARC AUX register interface, hence "reg" property

  is not specified.



Example:



	intc: interrupt-controller {

		compatible = "snps,archs-intc";

		interrupt-controller;

		#interrupt-cells = <1>;

		interrupts = <16 17 18 19 20 21 22 23 24 25>;

	};
