[PATCH v2 8/9] arm64: dts: ls1046a-qds: add mmio based mdio-mux nodes for FPGA

2022-09-15T23:38:13Z

There is mmio based mdio mux function in the FPGA device on ls1046a-qds
board. Add the mmio based mdio-mux nodes to ls1043a-qds boards and
add simple-mfd as a compatbile for the FPGA node to reflect the
multi-function nature of it.
