[SPARC64]: Fix powering off on SMP.
Doing a "SUNW,stop-self" firmware call on the other cpus is not the
correct thing to do when dropping into the firmware for a halt,
reboot, or power-off.
For now, just do nothing to quiet the other cpus, as the system should
be quiescent enough. Later we may decide to implement smp_send_stop()
like the other SMP platforms do.
Based upon a report from Christopher Zimmermann.
