Ext2nd Sensor Hot plug\Unplug

1.工程中主要根据两个接口来判断Sensor是否插入

BOOL DrvSensor_Det2ndSensor(void)
{
	return gpio_getPin(GPIO_914Q_LOCK);
	//return TRUE;
}

//--------------------------------------------------
BOOL Sensor_CheckExtSensor(void)
{
	__FUNC_TRACK__;
    static BOOL bFirstTime = TRUE;
    BOOL bDetExtSensor = DrvSensor_Det2ndSensor() ? TRUE : FALSE;

    if (bFirstTime)
    {
        bFirstTime = FALSE;
        g_bDetExtSensor = bDetExtSensor;
    }

    DBG_DUMP("^YSensor_CheckExtSensor: %d\r\n", bDetExtSensor);
	
	UI_SetData(FL_MOVIE_DUAL_REC, bDetExtSensor);
	
    return bDetExtSensor;
}

2.使用BOOL DrvSensor_Det2ndSensor(void)的部分：
