dma: add support for scatterlist to scatterlist copy
This adds support for scatterlist to scatterlist DMA transfers. A similar interface is exposed by the fsldma driver (through the DMA_SLAVE API) and by the ste_dma40 driver (through an exported function). This patch paves the way for making this type of copy operation a part of the generic DMAEngine API. Futher patches will add support in individual drivers. Signed-off-by: Ira W.
