  SVN rev 197492 on 2009-09-25 17:56:13Z by marius
  
  MFC: r197402
  
  - Add missing bus_dmamap_sync(9) calls for the work DMA map. Previously
    the work area was totally unsynchronized which means this driver only
    had a chance of working on x86 when no bounce buffers were involved,
    which isn't that likely given that support for 64-bit DMA is currently
    broken throughout ata(4).
  - Add necessary little-endian conversion of accesses to the work area,
    making this driver work on big-endian hosts. While at it, use the
    alignment-agnostic byte order encoders in order to be on the safe side.
  - Clear the reserved member of the SG list entries in order to be on the
    safe side. [1]
