video: fbdev: nvidia: deprecate pci_get_bus_and_slot()

Browse source 
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().

struct nvidia_par has a pointer to struct pci_dev. Use the pci_dev
member to extract the domain information and pass it to
pci_get_domain_bus_and_slot() function.
