make the dma interface useable.
make it so that pio devices must respond with some delay. dev/io_device.cc: don't forget to include dma_interface.hh so we could use it. dev/io_device.hh: the generic BusInterface isn't enough for doing DMA we need the actual DMAInterface --HG-- extra : convert_revision : 70298d33c8520a3f4ad11aa600825a8cec7e44bf
