Documentation/admin-guide: Document nomodeset kernel parameter
The nomodeset kernel command line parameter is not documented. Its name is quite vague and is not intuitive what's the behaviour when it is set. Document in kernel-parameters.txt what actually happens when nomodeset is used. That way, users could know if they want to enable this option.
