power: supply: max17042_battery: Follow MAX17055 POR sequence

Browse source

Wait until the MAX17055 is ready, leave hibernate around EZ Config,
and wait for ModelCfg.Refresh to clear as required by the power-on reset
initialization flow.

Restore HibCfg on every exit path. Keep failed restoration state so a
retry restores hibernate before starting a new initialization transaction.
