  SVN rev 204689 on 2010-03-04 05:23:08Z by neel
  
  Add support for CPUs with cache coherent DMA. The two main changes are:
  
  - We don't need to fall back to uncacheable memory to satisfy BUS_DMA_COHERENT
    requests on these CPUs.
  
  - The bus_dmamap_sync() is a no-op for these CPUs.
  
  A side-effect of this change is rename DMAMAP_COHERENT flag to
  DMAMAP_UNCACHEABLE. This conveys the purpose of the flag more accurately.
