[PATCH v5 5/7] dt-bindings: net: dsa: mediatek,mt7530: define port binding per switch

[Arınç ÜNAL]

Define DSA port binding per switch model as each switch model requires
different values for certain properties.

Define reg property on $defs as it's the same for all switch models.

Remove unnecessary lines as they are already included from the referred
dsa.yaml.
