    gc2033 can take raw photo
    sensor stream off ,mipi clk 没有关闭导致再stream on的时候mipi状态不对，dcam timeout

一定要把stream on/off 写好，开关mipi 使能输出

                [SENSOR_IOCTL_STREAM_ON].ops = c2390_drv_stream_on,
                [SENSOR_IOCTL_STREAM_OFF].ops = c2390_drv_stream_off,

严格按照sensor datasheet 写入开关mipi clk ，使能输出的时延
