I think this particularly makes sense in the light the other
at24 driver that was recently removed in commit 0113a99b8a75
("eeprom: Remove deprecated legacy eeprom driver").

The other problem with having two drivers is the need to
arbitrate between them, e.g. when you have a machine with
two at24 devices but want to use one of each for the two
subsystems. This does not really work with our DT probing
logic at the moment.
