This doesn't really eliminate pci_get_bus_and_slot(), because it doesn't 
force developers to support non-zero domains.  What's to stop a driver 
developer from doing this?

#define pci_get_bus_and_slot(b, d) pci_get_domain_bus_and_slot(0, b, d)

thereby completely ignoring what you're trying to do?
