Add compat_ioctl.  Although all structures are more or less same,
raw1394_iso_packets got pointer inside, and raw1394_cycle_timer got unwanted
padding in the middle.  I did not add any translation for ioctls passing array
of integers around as integers seem to have same size (32 bits) on all
architectures supported by Linux.
