dmaengine: correct invalid assumptions in the Kconfig text
This patch corrects recently changed (and now invalid) Kconfig descriptions for the DMA engine framework: - Non-Intel(R) hardware also has DMA engines; - DMA is used for more than memcpy and RAID offloading. In fact, on most platforms memcpy and RAID aren't factors, and DMA exists so that peripherals can transfer data to/from memory while the CPU does other work.

- Intel(R) offload engines enable offloading memory copies in the
- network stack and RAID operations in the MD driver.
+ DMA engines can do asynchronous data transfers without
+ involving the host CPU. Currently, this framework can be
+ used to offload memory copies in the network stack and
+ RAID operations in the MD driver.
