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.
