m68k: Don't select ARCH_HAS_DMA_PREP_COHERENT for nommu or coldfire
M68k only provides the arch_dma_prep_coherent symbol when an mmu is enabled and not on the coldfire platform. Fix the Kconfig symbol selection up to match this. Fixes: 69878ef47562 ("m68k: Implement arch_dma_prep_coherent()") Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
