From: Rafael J. Wysocki <rjw@xxxxxxx>
There is no reason why acpi_enable_wakeup_device() should be called
with interrupts disabled, because it doesn't access hardware. Thus
it is possible to move it next to acpi_enable_wakeup_device_prep()
and make the ACPI suspend, hibernate and poweroff code more
straightforward.
