power: supply: leds: Share trig pointer for online and charging_full

Either 5 different LED triggers are registered for battery power-supply
devices or a single online LED trigger is used for non battery power-supply
devices.

These 5 / 1 LED trigger(s) are never used at the same time. So there is
no need for a separate LED trigger pointer for the online trigger. Rename
the first battery trigger from charging_full_trig to just trig and use this
for the online trigger too.
