[PARISC] Add chassis_power_off routine
Define a chassis_power_off routine that machines which have a way to turn off the power supply can hook into. Formerly they were using pm_power_off, which is now being used by generic code. Make lasi.c use chassis_power_off instead of pm_power_off. Note, all machines need to call machine_power_off so that the switch can power off the machine, though halt -p may not necessarily be able to work properly on the machine.
