[PATCH 4/4] dt-bindings: net: dsa: mediatek,mt7530: update json-schema

[Arınç ÜNAL]

Update the json-schema for compatible devices.

- Define acceptable phy-mode values for CPU port of each compatible device.
- Remove requiring the "reg" property since the referred dsa-port.yaml
already does that.
- Require mediatek,mcm for the described MT7621 SoCs as the compatible
string is only used for MT7530 which is a part of the multi-chip module.
