[AVR32] Make dma_sync_*_for_cpu no-ops I don't think the dma_sync_*_for_cpu ever did anything useful. We flush the relevant cache lines when mapping the buffer or when calling dma_sync_*_for_device(), and the CPU isn't allowed to touch the buffer after that. In other words, if these functions actually have anything to flush from the caches, we're already in trouble. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
