dmaengine: remove DMA_MEMCPY_SG once again
This was removed before due to the complete lack of users, but
3218910fd585 ("dmaengine: Add core function and capability check for
DMA_MEMCPY_SG") and 29cf37fa6dd9 ("dmaengine: Add consumer for the new
DMA_MEMCPY_SG API function.") added it back despite still not having
any users whatsoever.
Fixes: 3218910fd585 ("dmaengine: Add core function and capability check for DMA_MEMCPY_SG")
Fixes: 29cf37fa6dd9 ("dmaengine: Add consumer for the new DMA_MEMCPY_SG API function.")
