PPC: dbdma: Wait for DMA until we have data

We should only start processing DMA requests when we have data to process.
Hold off working through the DMA shuffling until the IDE core told us that
it's ready.

This is required because the guest can program the DMA engine or the IDE
transfer first. Both are legal.
