[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. Signed-off-by: David S. Miller <davem@davemloft.net>
