V4L/DVB (9585): 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.
