try the debug patch that dumps the output pixel clock range of sdvo device

From the dmesg log we can get one message related with SDVO.
    >drm:intel_sdvo_debug_write], SDVOB: W: 16 48 3F 40 30 62 B0 32 40 (SDVO_CMD_SET_OUTPUT_TIMINGS_PART1)

    It seems that this SDVO device can't support the command of setting the output timing of SDVO device. I am not sure whether the high resolution is supported by this SDVO device.

    Will you please try the debug patch and attach the output of dmesg?

Thanks.
