Allows users to specify binary data to initialize an EEPROM, allowing users to
emulate data programmed at manufacturing time.
- Added init_rom and init_rom_size attributes to TYPE_AT24C_EE
- Added at24c_eeprom_init_rom helper function to initialize attributes
- If -drive property is provided, it overrides init_rom data
