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.
In order to use the same image for both boards, U-Boot is responsible for
detecting the revision and enabling/disabling DTS nodes.
So, to make it easy for users, lets add the pending U-Boot patches to build
in OpenWrt.
