Shiji Yang 0d4616b838 ramips: dts: add the missing interrupt properties for GPIO nodes
The Ralink GPIO driver supports irqchip function. Hence we need to
add "interrupt-parent" and "interrupt-controller" properties to make
sure it works properly. It is worth noting that all GPIO devices
share the same interrupt line.
