ec06c63cc7 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

e3fb3d1ad0 Misspeculation fix and (more importantly) change to allow for the ev6 style
physical addressing.  This has the uncacheable bit as bit 40 as opposed
to bit 39.  Additionally, we now support (at least superficially) a 44-bit
physical address.  To deal with superpage access in this scheme, any super
page access with either bit 39 or 40 set is sign extended.
