kstrto*: do not describe simple_strto*() as obsolete/replaced

The documentation of the kstrto*() functions describes kstrto*() as
"replacements" of the "obsolete" simple_strto*() functions.  Both of these
terms are inaccurate: they're not replacements because they have different
behaviour, and the simple_strto*() are not obsolete because there are
cases where they have benefits over kstrto*().

Remove usage of the terms "replacement" and "obsolete" in reference to
simple_strto*(), and instead use the term "preferred over".

Fixes: 4c925d60 ("kstrto*: add documentation")
Fixes: 885e68e8 ("kernel.h: update comment about simple_strto<foo>() functions")
