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.
