Staging: octeon-ethernet: Convert to use PHY Abstraction Layer.
The octeon-ethernet driver shares an mdio bus with the octeon-mgmt driver. Here we convert the octeon-ethernet driver to use the PHY Abstraction Layer. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
