Skip reading eeprom in newer Empia devices

Skip reading eeprom in newer Empia devices
Empia switched to a 16-bit addressable eeprom in newer devices. While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms). So just be safe and bail out of the function.
Thanks for Ray Lu from Empia for providing the em2874 datasheet.
