This fixes some incoherence between dma_map/free_coherent() and dma_sync_single_for_*() functions. While the former do appropriate cpu/dma conversions, the latter do not. This also fixes streaming DMA for MIPS CPUs and cleans up the interface somewhat. I want to get some thoughts on whether those are the appropriate changes to make and if I missed something important. The changes are split in two parts for now so it would be easier to review them. The first commit is the main part. It contains interface changes and arch-specific code adjustments. The second one just updates the functions usage in drivers.
