irqchip: DT bindings for Cortina Gemini irqchip

Browse Source 
This adds device tree bindings for the Cortina Gemini interrupt
controller. They are pretty standard.

* Cortina Systems Gemini interrupt controller
This interrupt controller is found on the Gemini SoCs.
Required properties:
- compatible: must be "cortina,gemini-interrupt-controller"
- reg: The register bank for the interrupt controller.
- interrupt-controller: Identifies the node as an interrupt controller
- #interrupt-cells: The number of cells to define the interrupts.
Must be 2 as the controller can specify level or rising edge
IRQs. The bindings follows the standard binding for controllers
with two cells specified in
interrupt-controller/interrupts.txt
Example:
interrupt-controller@48000000 {
compatible = "cortina,gemini-interrupt-controller";
reg = <0x48000000 0x1000>;
interrupt-controller;
#interrupt-cells = <2>;
};
