Revert "healthd: BatteryMonitor: doLogValues: reduce log level to debug"

This reverts commit aeccbb8f.

Reason for revert: needed for debug and investigations of battery and charging issues. The tooling depends on these lines (and have been for years). You should have these lines only on SOC changes and in the presence of a serious problem. Please do not remove logging without consulting with the BMS SW team first.
