dt-bindings: interrupt-controller: Convert marvell,armada-8k-pic to DT schema

Convert the Marvell 7K/8K PIC interrupt controller binding to schema
format. It's a straight-forward conversion of the typical interrupt
controller.

-Marvell Armada 7K/8K PIC Interrupt controller
----------------------------------------------
-
-This is the Device Tree binding for the PIC, a secondary interrupt
-controller available on the Marvell Armada 7K/8K ARM64 SoCs, and
-typically connected to the GIC as the primary interrupt controller.
-
-Required properties:
-- compatible: should be "marvell,armada-8k-pic"
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: the number of cells to define interrupts on this
-  controller. Should be 1
-- reg: the register area for the PIC interrupt controller
-- interrupts: the interrupt to the primary interrupt controller,
-  typically the GIC
-
-Example:
-
-       pic: interrupt-controller@3f0100 {
-               compatible = "marvell,armada-8k-pic";
-               reg = <0x3f0100 0x10>;
-               #interrupt-cells = <1>;
-               interrupt-controller;
-               interrupts = <GIC_PPI 15 IRQ_TYPE_LEVEL_HIGH>;
-       };
