m68knommu: add a local dma_sync_single_for_cpu() function
The onboard ethernet of many ColdFire parts uses DMA. The driver is being cleaned up to use the correct DMA handling functions, and m68knommuy currently does not implement dma_sync_single_for_cpu(). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
