IEEE 1394 subsystem updates:

- Replace made-up, unallocated Vendor and Model values of firewire-core's
     Configuration ROM register root directory by properly registered IDs.
     (These IDs are visible to peer nodes on the bus and locally via sysfs,
     but they are not involved in protocol matching or driver matching, nor
     are they used in stock udev rules.)
 
   - Remove some unneccessary code.
