Commit 834cbfe966bece50afded79da8e975d255bf0772
("drivers/dma: remove unused support for MEMSET operations")
removes MEMSET from dmaengine but does not completely removes it from
Marvell Orion (arch/arm/plat-orion) and XOR (drivers/dma/mv_xor).
This also fixes some compiler warnings about now obsolete functions by
removing those.
