Subject: Documentation/x86: remove a stray reference to pci-nommu.c

Documentation/x86: remove a stray reference to pci-nommu.c

This is just the minimal workaround.  The file is mostly either stale
and/or duplicative of Documentation/admin-guide/kernel-parameters.txt,
but that is much more work than I'm willing to do right now.
