Some interfaces are common across RDPs. Move the common nodes to ipq9574-rdp-common.dtsi like how it is done for IPQ5332. Use rdp specific dts file to include interfaces that vary across RDPs. For instance, IPQ9574 has 4 PCIE controllers. RDP417 enables PCIE0 and PCIE1 whereas RDP433 enables PCIE1, PCIE2 and PCIE3. With the introduction of the common RDP DTSI, - RDP433 gains SPI NOR support - All the IPQ9574 RDPs gains USB2 and USB3 support While at it, add support for WPS buttons.
