netdev: octeon_mgmt: Convert to use device tree.

The device tree will supply the register bank base addresses, make
register addressing relative to those.  PHY connection is now
described by the device tree.

The OCTEON_IRQ_MII{0,1} symbols are also removed as they are now
unused and interfere with the irq_domain used for device tree irq
mapping.
