battery: fix BQ27541/BQ27741 gas gauge driver
Update the code to be compatible with charge v2 expectations :
never return EC_ERROR_UNIMPLEMENTED for battery information else the
charge code continuously tries to read them again.
Fix the State Of Charge reading : on BQ27741 the gas gauge gets confused
if we do a 16-bit I2C read while a 8-bit read works perfectly.
