This results in right shift of data during a read. In order to ignore this bit a quirk can be added to send an extra zero bit after the read address. Add a quirk to ignore the zero bit sent before data by adding a zero bit after the read address.

The at24 driver should be used instead. So mark the eeprom driver as deprecated and give users some time to migrate. Then we can remove the legacy eeprom driver completely.
