[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.
