[PATCH 1/4] kernel-doc: Revert "scripts/kernel-doc: Processing -nofunc for functions only"

[Sean Christopherson <sean.j.christopherson@intel.com>]

Now that Docbook has been deprecated in favor of Sphinx, the -nofunction
option in kernel-doc is defunct, e.g. Sphinx doesn't currently support
it.  Furthermore, "functions only" behavior was used by Docproc to avoid
duplicating exported symbols, which is now handled by -export and
-internal.

The end goal is to enable using :nofunction: in .rst files to split
documentation of structures into separate categories.

This reverts commit 23aebb3c05f3b3fb06a68bf6b1539a05a5f8aaab.
