ARM: dts: keystone-k2g: Add PRUSS GPIO controller nodes

Add the PRUSS GPIO controller nodes on the 66AK2G SoC. These can
be used to send interrupts to specific PRUSS subsystem instances
present on the SoC. Each PRUSS is capable of receiving an interrupt
each from two such nodes. The IP is identical to that of the
equivalent node for the DSP present on 66AK2G SoC.
