While troubleshooting an issue with an user of the RDC r6040 driver
having compiled support for the fixed MDIO bus, I noticed that quite
some network drivers will have a MDIO bus named "0" most of the time.

Some network drivers already try to provide an unique MDIO bus name
using their PCI slot and function, this is okay.

Some other network drivers will format the name using their platform_device
id, which will usually result in a collision with the fixed MDIO bus
name ("0"), these drivers are fixed to use the following pattern instead:

<platform_device name>-<platform device id> which is unique

Finally the MDIO bus drivers themselves are patched to use an unique name
as well.

There is a potential to break user-space applications assuming there is a
specific MDIO bus named "0", "1" or other non-explanatory names like this.

Note that I compile tested most of the drivers on x86 and MIPS, ARM and Blackfin
drivers have not been compile tested.
