  Log:
  add a newbus method for obtaining the bus's bus_dma_tag_t...  This is
  required by arches like sparc64 (not yet implemented) and sun4v where there
  are seperate IOMMU's for each PCI bus...  For all other arches, it will
  end up returning NULL, which makes it a no-op...
  
  Convert a few drivers (the ones we've been working w/ on sun4v) to the
  new convection...  Eventually all drivers will need to replace the parent
  tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for
  each driver, and will require hand inspection...
