Subject: [PATCH 13/14] power: supply: bq25890: show VBAT as VOLTAGE_NOW

CONSTANT_CHARGE_VOLTAGE is a currently programmed CC voltage limit
and not instaneous reading of a VBAT. Move the measurement to correct
property. !online check is removed, as it is useful to read the voltage
when not charging.
