dma-mapping: provide a fallback dma_default_coherent
dma_default_coherent was decleared unconditionally at kernel/dma/mapping.c
but only decleared when any of non-coherent options is enabled in
dma-map-ops.h.
Guard the declaration in mapping.c with non-coherent options and provide
a fallback definition.
