dmaengine: correct invalid assumptions in the Kconfig text

Browse source 
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.
