Split eeprom.c into a base class base_eeprom_device and a serial-specific
subclass serial_eeprom_device. Moved the latter into its own file
eepromser.c and significantly cleaned up/simplified the code. The new
code should be functionally the same as the previous code, but expect that
to change soon. As a side-effect, the size and bus width of the EEPROM is now
specified in the ADD macro rather than in the interface structure.
