libcamera: v4l2_videodevice: Reduce zero sequence warning log level
The V4L2VideoDevice ensures that all sequence numbers for applications commence at zero from the libcamera perspective. This should be the behaviour expected by kernel drivers, but this is not always the case. This is handled internally to ensure consistency, and a warning is printed if the device does not start from zero. It was expected that the Warning would help highlight where kernel drivers should be fixed, but this has led to several false positive reports of failures where people have been concerned that this warning is a cause for unrelated issues. Lower the log level print to 'Info', to reduce the apparent severity of this warning. Info is likely more appropriate that Debug to continue to facilitate awareness of kernel drivers that could be improved, while not appearing to be a fault.
