Peter Ujfalusi fb9816f9d0 dmaengine: dmatest: Add support for completion polling 
With the polled parameter the DMA drivers can be tested if they can work
correctly when no completion is requested (no DMA_PREP_INTERRUPT and no
callback is provided).

If polled mode is selected then use dma_sync_wait() to execute the test
iteration instead of relying on the completion callback.
