backlight: deprecate pci_get_bus_and_slot()

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().

Hard-coding the domain as 0.
