dmaengine: idma64: make better performance on pause / resume Accordingly to the documentation the CH_DRAIN bit enforses single bursts when channel is going to be suspended. This, in case when channel will be resumed, makes data to flow in non-optimal mode until DMA returns to full burst mode. The fix differentiates pause / resume cycle from pause / terminate and sets CH_DRAIN bit accordingly.
