My change here[1] is going to effectively revert this. The RP1 stuff
needs to either be an overlay or not. We don't need both ways.
/aliases don't work for overlays. I suppose that could be added as a
fixup when applying. The kernel also assumes aliases are not dynamic
and uses indexes which aren't present, so even if it did work there
would still be problems. OTOH, if the bootloader might use the
ethernet controller, then why would this ever be an overlay in the
first place?

Turns out digging into RP1 stuff, it is a mess and needs reworking[2].

Right now, I just want the warning gone so I don't get further complaints[3].
