dt-bindings: interrupt-controller: Convert ti,cp-intc to DT schema

Convert the TI Common Platform interrupt controller binding to schema
format. It's a straight-forward conversion of the typical interrupt
controller.

-* TI Common Platform Interrupt Controller
-
-Common Platform Interrupt Controller (cp_intc) is used on
-OMAP-L1x SoCs and can support several configurable number
-of interrupts.
-
-Main node required properties:
-
-- compatible : should be:
-       "ti,cp-intc"
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source. The type shall be a <u32> and the value shall be 1.
-
-  The cell contains the interrupt number in the range [0-128].
-- ti,intc-size: Number of interrupts handled by the interrupt controller.
-- reg: physical base address and size of the intc registers map.
-
-Example:
-
-       intc: interrupt-controller@1 {
-               compatible = "ti,cp-intc";
-               interrupt-controller;
-               #interrupt-cells = <1>;
-               ti,intc-size = <101>;
-               reg = <0xfffee000 0x2000>;
-       };
