dma: move dma_map/unmap_single from ARM to common code

There's nothing ARM specific about these functions. Move them to a
common location, so other arches can use them as well.

This also fixes a bug on ARM MMU=n configurations:
Previously these two functions these functions only respected
dma-ranges translation when compiled with MMU support. DMA address
translation is applicable regardless of CPU use of MMU though.
Now, dma-ranges should be respected unconditionally.
