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>;
};
