ieee1394: sbp2: clean up function declarations
Remove unnecessary function prototypes. Remove variable names from function prototypes. Move declarations from sbp2.h to sbp2.c. Move definitions of driver templates together near the top of sbp2.c. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
