Do the same thing as in acpi_ac_resume.
BIOS on my laptop (HP Pavilion dv6-6179er) don't send proper
notifications when AC adapter is plugged/unplugged.
This change makes it possible to workaround the problem by using
acpid and a shell script.
This patch has the same effect as
commit 50a2bc5429f07ec4d53df2d287b03bdbceb281bb
"ACPI / AC: change notification handler type to ACPI_ALL_NOTIFY"
Aforementioned commit could be reverted.
