I'd rather go the other way and pass in the of_node to the bus and dimm registration routines. It's a generic property of the device so we should handle it like other generic device properties that get set at initialization time like 'attr_groups' in nvdimm_bus_descriptor, or a new parameter to nvdimm_create().
