Bring back dmaengine API support for scatter-gather memcpy's, which is a follow-up from a previous patch series in which I wrongly tried to implement the semantics of a MEMCPY_SG through the Slave SG interface. The second patch fixes a race condition that I observed when calling dmaengine_terminate_sync in the Xilinx DMA driver.
