lguest: use the PCI console device's emerg_wr for early boot messages.
This involves manually checking the console device (which is always in slot 1 of bus 0) and using the window in VIRTIO_PCI_CAP_PCI_CFG to program it (as we can't map the BAR yet). We could in fact do this much earlier, but we wait for the first write from the virtio_cons_early_init() facility. Signed-off-by: Rusty Russell <firstname.lastname@example.org>
