qdev_build_hotpluggable_device_list()
might describe better what function does

You can put object_child_foreach(peripheral, device_built_list, &list)
inside if this callback, see for example qmp_pc_dimm_device_list()

Also function would return ALL devices regardless of
whether they are hotpluggable or not.
"hotpluggable" property can be used to discard non hotpluggable devices.
