Subject: [PATCH 09/15] dt-bindings: net: mediatek,net: Correct bindings for
 MT7981

Different SoCs have different numbers of Wireless Ethernet
Dispatch (WED) units:
- MT7981: Has 1 WED unit
- MT7986: Has 2 WED units
- MT7988: Has 2 WED units

Update the binding to reflect these hardware differences. The MT7981
also uses infracfg for PHY switching, so allow that property.
