ACPI: AC: Properly notify powermanagement core about changes

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2078304

[ Upstream commit ac62f52138f752d6c74adc6321e4996d84caf5bb ]

The powermanagement core does various actions when a powersupply changes.
It calls into notifiers, LED triggers, other power supplies and emits an uevent.

To make sure that all these actions happen properly call power_supply_changed().
