From: Andrew Lunn <[email protected]>
The old way of performing a C45 bus transfer created a special
register value and passed it to the MDIO bus driver, in the hope it
would see the MII_ADDR_C45 bit set, and perform a C45 transfer. Now
that there is a clear separation of C22 and C45, this scheme is no
longer used. Remove all the #defines and helpers, to prevent any code
being added which tries to use it.
