Subject: [PATCH 7/9] eeprom: at24: add the at24cs series to the list of supported devices

The infrastructure for reading of the factory-programmed serial number
for at24cs EEPROM series is now in place. Add the chips that are actually
equipped with the serial number memory area to the list of supported
devices.
