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.

xilinx_dma: Fix read-after-free bug when terminating transfers
