drivers/dma: remove unused support for MEMSET operations
There have never been any real users of MEMSET operations since they
have been introduced in January 2007 by commit 7405f74badf4 ("dmaengine:
refactor dmaengine around dma_async_tx_descriptor"). Therefore remove
support for them for now, it can be always brought back when needed.
