Changes from v1:

- In 1/3 Add back check for non-OF objects in bgx_init_of_phy(). It
is probably not necessary, but better safe than sorry...

The firmware on many Cavium Thunder systems configures the MDIO bus
hardware to be probed as a PCI device. In order to use the MDIO bus
drivers in this configuration, we must add PCI probing to the driver.

There are two parts to this set of three patches:

1) Cleanup the PHY probing code in thunder_bgx.c to handle the case
where there is no PHY attached to a port, as well as being more
robust in the face of driver loading order by use of

2) Split mdio-octeon.c into two drivers, one with platform probing,
and the other with PCI probing. Common code is shared between the

Tested on several different Thunder and OCTEON systems, also compile
tested on x86_64.
