Bug description:
[Impact]
On some HP laptops, BIOS hotkeys don't work right after reboot, becuase
OS doesn't call _PTS to indicate ACPI it's rebooting.

[Fix]
Follow Windows and use S5 for reboot.

[Test case]
Reboot and see if hotkeys like F10/F11 can trigger BIOS functions.
Hotkeys work great with the patch applied.

[Where problems could occur]
If there are platforms don't expect S5 for reboot then there could be
unexpected result.
However Windows uses S5 so that's rather unlikely.
