Hmm, I don't get why Krzysztof said to just keep what is used in
existing device trees. The schema validator should describe what is
valid, and since the mt7530 driver does not care one way or another
(some drivers do explicitly parse the "ports"/"ethernet-ports" node),
then whatever is valid for the DSA core is also valid for the mt7530
bindings. And "ethernet-ports" is valid too, so I think it should be
accepted by mediatek.yaml...
