ACPI : do not use Lid and Sleep button for S5 wakeup
commit b7e383046c2c7c13ad928cd7407eafff758ddd4b upstream.
When system enters power off, the _PSW of Lid device is enabled.
But this may cause the system to reboot instead of power off.
A proper way to fix this is to always disable lid wakeup capability for S5.
