Subject: ACPI: Revert commit faee816b150238 due to regression

Commit faee816b1502385dc9bc5abf2960d1cc645844d1
"ACPI: don't enable control method power button as wakeup device
when Fixed Power button is used" caused the regression tracked
as http://bugzilla.kernel.org/show_bug.cgi?id=12091 (there are no
AC adapter events on Toshiba Portege R500) and the problem this
commit was intended to fix can be fixed differently.

For this reason, the author of the commit, Zhang Rui, has requested
that it be reverted.
