power: supply: bq25890: Call power_supply_changed() after updating input current or voltage
The bq25892 model relies on external charger-type detection and once
that is done the bq25890_charger code will update the input current
and if pumpexpress is used also the input voltage.
In this case, when the initial power_supply_changed() call is made
from the interrupt handler, the input settings are 5V/0.5A which
on many devices is not enough power to charge (while the device is on).
On many devices the fuel-gauge relies in its external_power_changed
callback to timely signal userspace about charging <-> discharging
status changes. Add a power_supply_changed() call after updating
the input current or voltage. This allows the fuel-gauge driver
to timely recheck if the battery is charging after the new input
settings have been applied and then it can immediately notify
userspace about this.

Fixes: eab25b4f93aa ("power: supply: bq25890: On the bq25892 set the IINLIM based on external charger detection")
