The old generic functions assume that the devices includes
an MDIO interface. This is true only for genuine ethernet.
Devices with a higher level of abstraction or based on different
technologies do not have it. So in preparation for
supporting that, we rename the old functions to something specific.

Hi Oliver

I would prefer this was called usbnet_get_link_ksettings_mii, since
this is using the old mii framework, not phylib and mdio drivers.  I
believe there are some USB drivers which do use mdio drivers and
phylib, and we should try to avoid getting things confused.

Since seems like you may respin with Andrew's suggestion: nit - extra
space before :.
