dt-bindings: interrupt-controller: Convert Broadcom STB L2 to YAML

Broadcom Generic Level 2 Interrupt Controller

Required properties:

- compatible: should be one of:

	      "brcm,hif-spi-l2-intc" or

	      "brcm,upg-aux-aon-l2-intc" or

	      "brcm,l2-intc" for latched interrupt controllers

              should be "brcm,bcm7271-l2-intc" for level interrupt controllers

- reg: specifies the 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. Should be 1.

- interrupts: specifies the interrupt line in the interrupt-parent irq space

  to be used for cascading

Optional properties:

- brcm,irq-can-wake: If present, this means the L2 controller can be used as a

  wakeup source for system suspend/resume.

Example:

hif_intr2_intc: interrupt-controller@f0441000 {

	compatible = "brcm,l2-intc";

	reg = <0xf0441000 0x30>;

	interrupt-controller;

	#interrupt-cells = <1>;

	interrupt-parent = <&intc>;

	interrupts = <0x0 0x20 0x0>;
