extcon: axp288: Add wakeup support

commit 9c94553099efb2ba873cbdddfd416a8a09d0e5f1 upstream.

On devices with an AXP288, we need to wakeup from suspend when a charger
is plugged in, so that we can do charger-type detection and so that the
axp288-charger driver, which listens for our extcon events, can configure
the input-current-limit accordingly.
