media: open.rst: remove the minor number range

Browse Source 
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.

Each driver thus loaded registers one or more device nodes with major
number 81 and a minor number between 0 and 255. Minor numbers are
allocated dynamically unless the kernel is compiled with the kernel
option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers
are allocated in ranges depending on the device node type (video, radio,
etc.).
