Debugging options for the DMA engine subsystem 



This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the DMA
engine subsystem, I got tired of editing the Makefile manually
each time I want to debug things in here, modelled this on the
debug switches for other subsystems and works like a charm when
working on our DMA engines.

          This is an option for use by developers; most people should

          say N here.  This enables DMA engine core and driver debugging.

          the DMA engine core and drivers.
