[PATCH net-next] dt-bindings: net: mdio: Document common properties

[Florian Fainelli]

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.
