arm64: dts: lx2160a-rdb: describe the QIXIS FPGA and two child GPIO controllers
Describe the FPGA present on the LX2160ARDB board as a simple-mfd I2C
device. The FPGA presents registers that deal with power-on-reset
timing, muxing, SFP cage monitoring and control etc.
Also add the two GPIO controllers responsible for monitoring and
controlling the SFP+ cages used for MAC5 and MAC6.
