pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
where a PCI device is present. This restricts the device drivers to be
reused for other domain numbers.

Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().

Use pci_get_domain_bus_and_slot() with a domain number of 0 as the code
is not ready to consume multiple domains and existing code used domain
number 0.

Looks to do what it says. I don't know if any of these call sites could
be improved to provide the domain, but that's not really your problem.

I tried to fix the places where I can at the rest of the series. I even took
a stab at fixing powerpc. There were places where the domain information was
not available and I couldn't locate where to extract it. I decided to leave it
as it is and hope that someone someday may expand the powerpc PCI adaptation.
