dt-bindings: gpio: uniphier: add UniPhier GPIO binding
This GPIO controller is used on UniPhier SoC family. The vendor specific property "socionext,interrupt-ranges" is for specifying interrupt mapping to the parent interrupt controller because the mapping is not contiguous. It works like "ranges", but transforms "interrupts" instead of "reg".
