Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().
Hard-code the domain number as 0 for the AMD IOMMU driver.

pci_get_bus_and_slot() appears to (now) be a convenience function that
wraps pci_get_domain_bus_and_slot() while using a 0 for the domain
value. Exactly what you are doing here, albeit in a more overt way.
How is this patch advantageous? Seems to me that if other domains need
to be enabled, that driver could be changed if and when that requirement
arises.
But perhaps I'm missing a nuance here.
