The Realtek mdio bus operations are based on the port number. As
of now the driver exposes a single bus with a 1:1 mapping between
phy and port. This will change in the future when the driver
exposes multiple busses. This will need a mapping - e.g.
- bus 0, phy 23 -> read/write port 23
- bus 1, phy 0 -> read/write port 24
Provide a rtmdio_phy_to_port() indirection function that will
lookup the port number based on a bus and a phy. For now it
will only run some basic sanity checks and return the given
input address (because of 1:1 mapping).
