	syssrc/sys/arch/arm/include: bus.h

Log Message:
* Add an ARM32_DMAMAP_COHERENT flag to indicate that a loaded DMA
  map contains "coherent" (non-cached in ARM-land) mappings.
* Set ARM32_DMAMAP_COHERENT in the map at the start of a load operation,
  and clear it in _bus_dmamap_load_buffer() if we encounter any cacheable
  mappings.
* In _bus_dmamap_sync(), if the map is marked COHERENT, skip any cache
  flushing.
