dmaengine: dw-edma: Fix to change for continuous transfer

Browse source

[ Upstream commit a251994a44 ]

The dw-edma driver stops after processing a DMA request even if a request
remains in the issued queue, which is not the expected behavior. The DMA
engine API requires continuous processing.

Add a trigger to start after one processing finished if there are requests
remain.
