power: pm8921-bms: adjust the pon ocv

The power on open circuit voltage (pon ocv) is always reported higher.
Reduce 15mV from the pon ocv.

Also on chips trimmed with revision lower than 9 - there is an additional
error on all the battery voltage readings. Use the trim program version
and the trim register to nullify this error.
