[PATCH V4 04/26] ata: deprecate pci_get_bus_and_slot()

[PATCH V4 04/26] ata: deprecate pci_get_bus_and_slot()

[Sinan Kaya]

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() and extract the actual domain number
from the pdev passed in.
