[PATCH] kill useless exports and bookkeeping in bt878.c

[PATCH] kill useless exports and bookkeeping in bt878.c

[Christoph Hellwig]

 - no point in exporting bt878_init_module and bt878_cleanup_module,
   they are always called on module load/removal
 - bt878_find_audio_dma and the registered bookeeping is utterly
   pointless as a registration always heppens on load anyway
