firewire: Use lib/ implementation of CRC ITU-T.
With the CRC ITU-T implementation available in lib/ we can use that instead. This also fixes a bug in the topology map crc computation. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (fixed Kconfig)
