Pull dmaengine updates from Vinod Koul:
 "This one features the usual updates to the drivers and one good part
  of removing DA_SG from core as it has no users.

  Summary:

   - Remove DMA_SG support as we have no users for this feature
   - New driver for Altera / Intel mSGDMA IP core
   - Support for memset in dmatest and qcom_hidma driver
   - Update for non cyclic mode in k3dma, bunch of update in bam_dma,
     bcm sba-raid
   - Constify device ids across drivers"
