Bring back dmaengine API support for scatter-gather memcpy's.

Changes in patch v2:
  * Expanded API function documentation to elaborate on its semantics,
    limitations and corner case behaviour.
  * Broke the patch series into three different ones: documentation, core
    API change and consumer driver

v1 - https://lore.kernel.org/dmaengine/20210706234338.7696-1-adrian.martinezlarumbe@imgtec.com

Adrian Larumbe (3):
  dmaengine: Add documentation for new memcpy scatter-gather function
  dmaengine: Add core function and capability check for DMA_MEMCPY_SG
  dmaengine: Add consumer for the new DMA_MEMCPY_SG API function.
