parisc: Prevent panic at system halt

Browse source

When issuing a "shutdown -h now", the reboot syscall calls kernel_halt()
which shouldn't return, otherwise one gets this panic:

reboot: System halted
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000
CPU: 0 PID: 1 Comm: systemd-shutdow Not tainted 4.16.0-32bit+ #560
Backtrace:
 [<1018a694>] show_stack+0x18/0x28

Fix it by letting machine_halt() call machine_power_off() which doesn't
return.
