  Log:
  Rename BUS_DMAMEM_NOSYNC to BUS_DMA_COHERENT.
  
  The current name is confusing, because it indicates to
  the client that a bus_dmamap_sync() operation is not
  necessary when the flag is specified, which is wrong.
  
  The main purpose of this flag is to hint the underlying
  architecture that DMA memory should be mapped in a coherent
  way, but the architecture can ignore it.  But if the
  architecture does supports coherent mapping of memory, then
  it makes bus_dmamap_sync() calls cheap.
  
  This flag is the same as the one in NetBSD's Bus DMA.
