0201e2da65 Add (virtual) interrupt to PAPR virtual tty device 
Now that we have implemented the PAPR "xics" virtualized interrupt
controller, we can add interrupts in PAPR VIO devices.  This patch adds
interrupt support to the PAPR virtual tty/console device.

4040ab7237 Implement the bus structure for PAPR virtual IO 
This extends the "pseries" (PAPR) machine to include a virtual IO bus
supporting the PAPR defined hypercall based virtual IO mechanisms.

So far only one VIO device is provided, the vty / vterm, providing
a full console (polled only, for now).
