    mvebu: cortex-a53: fix Methode eDPU migration to upstream DTS
    
    Migration of the eDPU DTS to upstream one broke the eDPU plus model
    since the required ethernet aliases are missing and U-Boot then cannot
    find the required ethernet nodes.
    
    So, after sending the required fix upstream, lets apply it in OpenWrt
    as well.

+Subject: [PATCH] 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.
