Some of the PHY and MDIO drivers refer to the COPYING file in the main
directory of this archive. This is the main license for Linux, thus
GPLv2 plus syscall extension.
Fixup the MODULE_LICENSE() where needed and add an SDPX header for
GPLv2.

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.
