As the comment says: U-Boot
(https://elixir.bootlin.com/u-boot/latest/source/board/CZ.NIC/turris_mox/turris_mox.c#L728)
sets up status = "okay" for these nodes depending on the MOXTET
configuration. It doesn't look as if it's doing that by alias, just by
path ("%s/switch%i@%x").

I have a Turris MOX, please allow me some time to test if the node name
change is going to be significant and cause regressions. I expect the
answer to be yes (sadly).
