[PATCH net-next 09/12] amd-xgbe: Replace MII_ADDR_C45 with XGBE_ADDR_C45

[Michael Walle]

From: Andrew Lunn <andrew@xxxxxxx>

The xgbe driver reuses MII_ADDR_C45 for its own purpose. The values
derived with it are never passed to phylib or a linux MDIO bus driver.
In order that MII_ADDR_C45 can be removed, add an XGBE specific
