Gpio charger should notify if the gpio state had changed
during suspend. This will send a CHANGED event each time
the system resumes, ensuring a plug/unplug of the charger
is not missed.

This will also setup the pm hooks for suspend to disk.
And SIMPLE_DEV_PM_OPS will also ignore the callbacks if CONFIG_PM_SLEEP is not
set, so it can go outside of the #ifdef CONFIG_PM_SLEEP and you can also get
rid of the #ifdef ...
