The realtek-mdio driver is an MDIO driver and it must be inserted inside
an MDIO node.
The compatible string is only used to identify which (silicon) family the
switch belongs to. Roughly speaking, a family is any set of Realtek switches
whose chip identification register(s) have a common location and semantics.
The different models in a given family can be automatically disambiguated by
parsing the chip identification register(s) according to the given family,
avoiding the need for a unique compatible string for each model.
