power: supply: bq24190_charger: Call power_supply_changed() for relevant component

commit 2d9fee6a42ea170e4378b3363a7ad385d0e67281 upstream.

We wrongly get uevents for bq24190-charger and bq24190-battery on every
register change.

Fix by checking the association with charger and battery before
emitting uevent(s).
