Subject: [PATCH] ACPI : do not use Lid and Sleep button for S5 wakeup

When system enters power off, the _PSW of Lid device is enabled.  
But this may cause the system to reboot instead of power off.

https://bugzilla.kernel.org/show_bug.cgi?id=35262

A proper way to fix this is to always disable lid wakeup capability
for S5.
