Debugging options for the DMA engine subsystem

Browse Source 
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.

This is an option for use by developers; most people should
say N here. This enables deeper (more verbose) debugging of
the DMA engine core and drivers.
