ieee1394: save one word in struct hpsb_host
hpsb_host.config_roms is a bitfield of which only one bit is currently used. hpsb_host.update_config_rom is only a Boolean. Neither one is accessed in hot code paths or with alignment requirements. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
