Log message:
Implement a "machine xir" ddb command, making it possible to send an
External Initiated Reset (XIR) to processors. A XIR is non-maskable and will
drop us at the PROM ok prompt. This makes it possible to diagnose problems
where a CPU is spinning with interrupts disabled.
For now, this is only supported on machines with bbc(4).
