PCI: add pci_get_domain_bus_and_slot function
Added the pci_get_domain_and_slot_function which is analogous to pci_get_bus_and_slot. It returns a pci_dev given a domain (segment) number, bus number, and devnr. Like pci_get_bus_and_slot, pci_get_domain_bus_and_slot holds a reference to the returned pci_dev. Converted pci_get_bus_and_slot to a wrapper that calls pci_get_domain_bus_and_slot with the domain hard-coded to 0. This routine was patterned off code suggested by Bjorn Helgaas.
