ARM PL061 GPIO controller
Required properties:
- compatible : "arm,pl061", "arm,primecell"
- #gpio-cells : Should be two. 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)
- gpio-controller : Marks the device node as a GPIO controller.
- interrupts : Interrupt mapping for GPIO IRQ.
