media: open.rst: remove the minor number range
minor numbers use to range between 0 to 255, but that was changed a long time ago. While it still applies when CONFIG_VIDEO_FIXED_MINOR_RANGES, when the minor number is dynamically allocated, this may not be true. In any case, this is not relevant, as udev will take care of it. So, remove this useless misinformation.
