Use stateless object_property_find() to do that, and move the rest of BSEL handling into build_append_pcihp_slots() where it belongs. This cleans up generic code a bit from hotplug stuff and follow up patch will remove remaining call to build_append_pcihp_slots() from generic code, making it possible to use without ACPI PCI hotplug dependencies.
