ieee1394: remove old isochronous ABI
Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. 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 interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
