hw/nvram/fw_cfg: Pass QOM parent to fw_cfg_add_file_from_generator()

Browse source 
Currently fw_cfg_add_file_from_generator() is restricted
to command line created objects which reside in the
'/objects' QOM container. In order to extend to other
types of containers, pass the QOM parent by argument.
