Subject: [PATCH] pipeline: v4l2_subdevice: Add color space to format string
 representation

To debug color issues in a pipeline it is necessary to know the color
space used. Therefore add the color space to the string representation
of V4L2SubdeviceFormat that is returned by toString() and operator<<().
