static void versatile_pci_register_types(void)
cannot_destroy_with_object_finalize_yet was added by 4c315c2 ("qdev: Protect device-list-properties against broken devices") because "realview_pci" and "versatile_pci" were hanging during "device-list-properties" cleanup (an infinite loop in bus_unparent()). We have this problem because the child is not removed from the list of the PCI bus child because it has no defined parent: qdev_set_parent_bus() set the device parent_bus pointer to bus, and adds the device in the bus children list, but doesn't update the device parent pointer. To fix the problem, move all the involved parts to the realize function.
