ACPI / Battery: Add the hibernation process in the battery_notify()

The Commit 25be58215 has added a PM notifier to refresh the sys in order
to deal with the unit change of the Battery Present Rate. But it just
consided the suspend situation. The problem also will happen during the
hibernation according the bug 28192.
