gpio: pl061: add DT binding support
This adds devicetree binding support to the ARM pl061 driver removing the platform_data dependency. When DT binding is used, the gpio numbering is assigned dynamically. For now, interrupts are not supported with DT until irqdomains learn dynamic irq assignment. Rather than add another case of -1, updating the driver to use NO_IRQ.
