phy: mdio-octeon: Refactor into two files/modules
A follow-on patch uses PCI probing to find the Thunder MDIO hardware. In preparation for this, split out the common code into a new file mdio-cavium.c, which will be used by both the existing OCTEON driver, and the new Thunder PCI based driver. As part of the refactoring simplify the struct cavium_mdiobus by removing fields that are only ever used in the probe function and can just as well be local variables. Use readq/writeq in preference to readq_relaxed/writeq_relaxed as the relaxed form was an optimization for an early chip revision, and the MDIO drivers are not performance bottlenecks that need optimization in the first place.
