m68k: don't provide arch_dma_alloc for nommu/coldfire
Coldfire cores configured with a data cache can't provide coherent
DMA allocations at all.
Instead of returning non-coherent kernel memory in this case,
return NULL and fail the allocation.
The only driver that used to rely on the previous behavior (fec) has
been switched to use non-coherent allocations for this case recently.
