enetc: Make mdio accessors more generic

Refactoring needed to support multiple MDIO buses.
'mdio_base' - MDIO registers base address - is being parameterized.
The MDIO accessors are made more generic to be able to work with
different MDIO register bases.
Some includes get cleaned up in the process.
