- Use the streaming cache unless BUS_DMA_COHERENT is specified. Since
  r220375 all drivers enabled in the sparc64 GENERIC should be either
  correctly using bus_dmamap_sync(9) calls or supply BUS_DMA_COHERENT
  when appropriate or as a workaround for missing bus_dmamap_sync(9)
  calls (sound(4) drivers and partially sym(4)). In at least some
  configurations taking advantage of the streaming cache results in
  a modest performance improvement.
- Remove the memory barrier for BUS_DMASYNC_PREREAD which as the
  comment already suggested is bogus.
- Add my copyright for having implemented several things like support
  for the Fire and Oberon IOMMUs, taking over PROM IOMMU mappings etc.
