net: eepro100: Pass PCI BDF into bus_to_phys()/phys_to_bus()

This is a trick in preparation for adding DM support. By passing in
the PCI BDF into the bus_to_phys()/phys_to_bus() macros and calling
that dev, we can substitute dev with udevice when DM support lands
and do minor adjustment to the macros to support both DM and non-DM
operation. No functional change.
