This patch adds the necessary "hook" to allow SGI/SN machines to perform a system power off upon a 'init 0', 'halt -p', 'poweroff' or 'shutdown -h'. The "hook" is to set the pm_power_off callback to ia64_sn_power_down(). pm_power_off is checked in machine_power_off()/do_poweroff() and, if set, is executed. ia64_sn_power_down() is a function already present (but not used currently) in the sn kernel. ia64_sn_power_down() makes a SAL call to execute the power off.
