Coldfire cores configured without a data cache are DMA coherent and
should thus simply use the simple coherent version of dma-direct.
Introduce a new COLDFIRE_COHERENT_DMA Kconfig symbol as a convenient
short hand for such configurations, and a M68K_NONCOHERENT_DMA symbol
for all cases where we need to build non-coherent DMA infrastructure
to simplify the Kconfig and code conditionals.
Not building the non-coherent DMA code slightly reduces the code
size for such configurations.
