dmaengine: sprd: Fix the DMA link-list configuration
For the Spreadtrum DMA link-list mode, when the DMA engine got a slave
hardware request, which will trigger the DMA engine to load the DMA
configuration from the link-list memory automatically. But before the
slave hardware request, the slave will get an incorrect residue due
to the first node used to trigger the link-list was configured as the
last source address and destination address.
Thus we should make sure the first node was configured the start source
address and destination address, which can fix this issue.
