Subject: [PATCH 5/7] mm/damon/Kconfig: Notify debugfs deprecation plan

Commit b18402726bd1 ("Docs/admin-guide/mm/damon/usage: document DAMON
sysfs interface") announced the DAMON debugfs interface deprecation
plan, but it is not so aggressively announced.  As the deprecation time
is coming, this commit makes the announce more easy to be found by
adding the note to the config menu of DAMON debugfs interface.
