Add locking and always use shadows for registers controlling GPIO pins

ieee1394: remove old isochronous ABI
Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}"

This patch also removes the underlying facilities in ohci1394 and
disables them in pcilynx. That is, hpsb_host_driver.devctl() and
hpsb_host_driver.transmit_packet() are no longer used for iso reception
and transmission.
Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso

longer useful for isochronous applications.
