pci_bus_find_domain_nr() retrieves the host bridge domain number in a DT specific way. Factor our pci_bus_find_domain_nr() in a separate DT function (ie of_pci_bus_find_domain_nr()) so that DT code is self contained, paving the way for retrieving domain number in pci_bus_find_domain_nr() with additional firmware methods (ie ACPI).
