PATCH 2/2 power_supply: ds2781: Use DS2781_PARAM_EEPROM_SIZE and DS2781_USER_EEPROM_SIZE

Since we have defined DS2781_PARAM_EEPROM_SIZE and DS2781_USER_EEPROM_SIZE, use them to simplify the code.

Hi

both patches look good, thank you
Greg, please pull it into your tree

Me? Why?

I'm not the drivers/power/ maintainer, please send this to the proper person.

thanks,
