Docs/admin-guide/mm/damon/usage: note DAMON debugfs interface deprecation plan

Browse Source 
Commit b18402726b ("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 at the beginning of the DAMON debugfs interface usage document.

debugfs Interface
=================
.. note::
DAMON debugfs interface will be removed after next LTS kernel is released, so
users should move to the :ref:`sysfs interface <sysfs_interface>`.
DAMON exports eight files, ``attrs``, ``target_ids``, ``init_regions``,
``schemes``, ``monitor_on``, ``kdamond_pid``, ``mk_contexts`` and
``rm_contexts`` under its debugfs directory, ``<debugfs>/damon/``.
