    ieee1394: drop csr1212's support for external compilation
    
    csr1212 was written to be compiled either as part of the ieee1394 kernel
    driver or of an anticipated IEEE 1212 userspace library.  We now drop
    support for the latter.  The costs in terms of code footprint and depth
    of abstraction are not countered by any actual benefit.
    
    Also remove some obsolete #includes.
