marius fd213ef8e2 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.
