Log:
  MFC r234540:
  
  Fix the following clang warning in dpt(4):
  
    sys/dev/dpt/dpt_scsi.c:612:18: error: implicit truncation from 'int' to bitfield changes value from -2 to 2 [-Werror,-Wconstant-conversion]
      dpt->cache_type = DPT_CACHE_WRITEBACK;
                      ^ ~~~~~~~~~~~~~~~~~~~
  
  by defining DPT_CACHE_WRITEBACK as 2, since dpt_softc::cache_type is an
  unsigned bitfield.  No binary change.
