'reg' without any constraints allows multiple items which is not the
intention for Ethernet controller's port number.

Shouldn't this constrained by dsa-port.yaml (or the under review 
ethernet switch schemas that split out the DSA parts)?

dsa-port should indeed have such change (I'll send one), but these
schemas do not reference it.

They reference only ethernet-controller, which does not even mention
'reg' port. I'll describe it better in commit msg.

ethernet-switch is not yet referenced in the schemas changed here. It
would not be applicable to asix,ax88178.yaml and microchip,lan95xx.yaml.
To others - probably it would be applicable.

Best regards,
Krzysztof
