Pull dmaengine updates from Vinod Koul:
 "New support / Core:

   - Remove DMA_MEMCPY_SG for lack of users

   - Tegra 234 dmaengine support

   - Mediatek MT8365 dma support

   - Apple ADMAC driver

  Updates:

   - Yaml conversion for ST-Ericsson DMA40 binding and Freescale edma

   - rz-dmac updates and device_synchronize support

   - Bunch of typo in comments fixes in drivers

   - multithread support in sf-pdma driver"
