PM: Make ACPI wakeup from S5 work again when CONFIG_PM_SLEEP is unset 



Commit 074037ec (PM / Wakeup: Introduce wakeup source objects and
event statistics (v3)) caused ACPI wakeup to only work if
CONFIG_PM_SLEEP is set, but it also worked for CONFIG_PM_SLEEP unset
before.  This can be fixed by making device_set_wakeup_enable(),
device_init_wakeup() and device_may_wakeup() work in the same way
as before commit 074037ec when CONFIG_PM_SLEEP is unset.
