Nintendo Wii (Hollywood) GPIO controller

Required properties:

• compatible: “nintendo,hollywood-gpio”
• reg: Physical base address and length of the controller’s registers.
• gpio-controller: Marks the device node as a GPIO controller.
• #gpio-cells: Should be <2>. The first cell is the pin number and the
  second cell is used to specify optional parameters:
  • bit 0 specifies polarity (0 for normal, 1 for inverted).

Optional properties:

• ngpios: see Documentation/devicetree/bindings/gpio/gpio.txt
• interrupt-controller: Marks the device node as an interrupt controller.
• #interrupt-cells: Should be two.
• interrupts: Interrupt specifier for the controller’s Broadway (PowerPC)
  interrupt.
• interrupt-parent: phandle of the parent interrupt controller.

Example:

GPIO: gpio@d8000c0 {
    #gpio-cells = <2>;
    compatible = "nintendo,hollywood-gpio";
    reg = <0x0d8000c0 0x40>;
    gpio-controller;
    ngpios = <24>;
