power: supply: max17042_battery: Program MAX17055 EZ Config values

Browse source

MAX17055 EZ Config requires DesignCap, dQAcc, IChgTerm, and dPAcc to
be programmed coherently. Write each supplied stable register once, wait
1 ms, and verify its read-back instead of relying on the unchecked generic
POR override path.

Derive dPAcc from the effective DesignCap, dQAcc, and ModelCfg values so
the accumulator matches the selected charge-voltage range. Propagate all
read, write, verification, and range errors to the retrying init worker.
