[PATCH 03/15] power: supply: cpcap-battery: Fix battery low status reporting

[Arthur Demchenkov <spinal.by@gmail.com>]

If we hit battery low once, we should stick on reporting it until the
charger is connected. This way low->counter_uah will be updated
properly, and that will allow us to get more accurate charge_full value.
