Subject: [Intel-wired-lan] [PATCH v3 04/30] docs: kdoc_parser: don't
mangle with function defines

Mangling with #defines is not nice, as we may end removing the macro
names, preventing several macros from being properly documented.

Also, on defines, we have something like:

	#define foo(a1, a2, a3, ...)			 \
		/* some real implementation */

The prototype part (first line on this example) won't contain any
macros, so no need to apply any regexes on it.

With that, move the apply_transforms() logic to ensure that it will be
called only on functions.
