-Synchronise a single contiguous or scatter/gather mapping.  All the
-parameters must be the same as those passed into the single mapping
-API.

-Notes:  You must do this:
-
-- Before reading values that have been written by DMA from the device
-  (use the DMA_FROM_DEVICE direction)
-- After writing values that will be written to the device using DMA
-  (use the DMA_TO_DEVICE) direction
-- before *and* after handing memory to the device if the memory is
-  DMA_BIDIRECTIONAL
