arm64: dts: marvell: uDPU: add ethernet aliases

On eDPU plus, which is an updated revision of eDPU which uses an external
MV88E6361 switch we are relying on U-Boot to detect the board, and then
enable and disable the required nodes for that revision.

However, it seems that I missed adding the required aliases for ethernet
controllers, and this worked as in OpenWrt we had added those locally.
