  Log:
  SVN rev 187240 on 2009-01-14 21:04:23Z by marius
  
  MFC: r185108
  
  Given that the buffer dcons_crom(4) exposes is used for both input
  and output, set BUS_DMA_COHERENT when creating the DMA map used for
  loading the buffer. As a side-effect this solves locking issues on
  sparc64 when dcons(4) calls bus_dmamap_sync(9) while in an interrupt
  filter, which are executed in a critical section, and iommu(4) has
  to use a sleep lock when taking advantage of the streaming buffer.
