power: pcf50633: properly reenable charging when the supply conditions change
If chgmod == BATFULL, setting chgena has no effect. Datasheet says we
need to set resume instead but when autoresume is used resume doesn't
work. Clear and set chgena instead.
This enables a user to force charging by re-plugging USB even when the
charger entered Battery Full mode, might be handy before a long trip.
