dt-bindings: intc: Convert ingenic,intc.txt to YAML

Convert the ingenic,intc.txt doc file to ingenic,intc.yaml.

Some compatible strings now require a fallback, as the controller
generally works the same across the SoCs families.

-Ingenic SoC Interrupt Controller
-
-Required properties:
-
-- compatible : should be "ingenic,<socname>-intc". Valid strings are:
-    ingenic,jz4740-intc
-    ingenic,jz4725b-intc
-    ingenic,jz4770-intc
-    ingenic,jz4775-intc
-    ingenic,jz4780-intc
-- 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.
-- interrupts : Specifies the CPU interrupt the controller is connected to.
-
-Example:
-
-intc: interrupt-controller@10001000 {
-	compatible = "ingenic,jz4740-intc";
-	reg = <0x10001000 0x14>;
-
-	interrupt-controller;
-	#interrupt-cells = <1>;
-
-	interrupt-parent = <&cpuintc>;
-	interrupts = <2>;
-};
