    power: supply: bq27xxx: After charger plug in/out wait 0.5s for things to stabilize
    
    [ Upstream commit 59a99cd462fbdf71f4e845e09f37783035088b4f ]
    
    bq27xxx_external_power_changed() gets called when the charger is plugged
    in or out. Rather then immediately scheduling an update wait 0.5 seconds
    for things to stabilize, so that e.g. the (dis)charge current is stable
    when bq27xxx_battery_update() runs.
