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
