We are not initializing HW propperly, when using MY_CORE_ONLY, so I2C bus is not working

Seems to still be an issue when running SensebenderGatewaySerial sketch from development branch. Execution halts when Wire.endTransmission(); is hit in extEEPROM.cpp.

I2C hardware probably still not initialized correctly.

Btw shouldn't MY_EXT_EEPROM_SIZE be 32 kbits?
