Sync with the ADMA2 implementation in imxesdhc(4):
Map the ADMA2 descriptor table use BUS_DMA_COHERENT and add a missing
bus_dmamap_sync(9). Doesn't really fix anything, but adding the missing
sync makes the code more correct. Using BUS_DMA_COHERENT avoids some
cache flushes on architectures that implement it.
