power: pm8921-bms: account for sleep time in ADC calibration
Currently, the system calibrates the CCADC and HKADC every 10 minutes of
kernel time. However, this does not count sleep time, which could make
calibration much more infrequent.
Fix this by saving the time of the last calibration for both ADCs and
immediately calibrate upon resume if the elapsed time is longer than the
calibration period.
