dmaengine: Revert "drivers/dma: remove unused support for MEMSET operations"
This reverts commit 48a9db462d99494583dad829969616ac90a8df4e. Some platforms actually need support for the memset operations. Bring it back. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
