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.
