Subject: [PATCH net-next v2 1/2] dt-bindings: net: mdio: Document common properties

Some of the properties pertaining to the broken turn around or resets
were only documented in ethernet-phy.yaml while they are applicable
across all MDIO devices and not Ethernet PHYs specifically which are a
superset.
