Fix issue when BaseDebugLibSerialPort is combined with BaseSerialPortLibNull.  It will ASSERT() due to the recent addition of a CONSTRUCTOR to BaseDebugLibSerialPort that calls SerialPortInitialize().
The fix is to change SerialPortInitialize() to always return RETURN_SUCCESS instead of RETURN_UNSUPPORTED.
