mips: dts: realtek: Add gpio block

The RTL9300 has a block of GPIOs included in the SoC. Add these to the
devicetree.

This is taken from openwrt[1] the differences are removing the
unnecessary second cell from the interrupt and removing the -controller
from the node name to conform to the dtschema.
