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

In the future, this can be used for actual data, but for now, it's
so that devices can respond to timing accesses properly. This way,
an uncached access on a bus further away will take longer to respond.

dev/alpha_console.hh:
suport the separate IO bus
