arm64: dts: marvell: eDPU: add support for version with external switch 



New revision of eDPU uses an Marvell MV88E6361 switch to connect the SFP
cage and G.hn IC instead of connecting them directly to the ethernet
controllers.

U-Boot will enable the switch node and disable the unused ethernet
controller.
