dt-bindings: gpio: Convert ti,twl4030-gpio to DT schema 



Convert the TI TWL4030 PMIC GPIO binding to DT schema format. The number
of #interrupt-cells was wrong compared to what is in use. Correct it to
be 1.

twl4030 GPIO controller bindings



Required properties:

- compatible:

  - "ti,twl4030-gpio" for twl4030 GPIO controller

- #gpio-cells : Should be two.

  - first cell is the pin number

  - second cell is used to specify optional parameters (unused)

- gpio-controller : Marks the device node as a GPIO controller.

- #interrupt-cells : Should be 2.

- interrupt-controller: Mark the device node as an interrupt controller

  The first cell is the GPIO number.

  The second cell is not used.

- ti,use-leds : Enables LEDA and LEDB outputs if set

- ti,debounce : if n-th bit is set, debounces GPIO-n

- ti,mmc-cd : if n-th bit is set, GPIO-n controls VMMC(n+1)

- ti,pullups : if n-th bit is set, set a pullup on GPIO-n

- ti,pulldowns : if n-th bit is set, set a pulldown on GPIO-n



Example:



twl_gpio: gpio {

    compatible = "ti,twl4030-gpio";

    #gpio-cells = <2>;

    gpio-controller;

    #interrupt-cells = <2>;

    interrupt-controller;

    ti,use-leds;

};
