Subject: [PATCH 6/6] Docs/admin-guide/mm/damon/usage: use a list for 'state' sysfs file input commands

There are eight command inputs for 'state' DAMON sysfs file, and those
are verbosely explained in multiple paragraphs.  It is not easy to find
explanation of specific command, and getting whole picture of supported
commands.  Replace the paragraphs with a list.

-Writing ``update_schemes_stats`` to ``state`` file updates the

+Users can write below commands for the kdamond to the ``state`` file.

+- ``on``: Start running.
+- ``off``: Stop running.
+- ``commit``: Read the user inputs in the sysfs files except ``state`` file
+  again.
+- ``commit_schemes_quota_goals``: Read the DAMON-based operation schemes'
+  :ref:`quota goals <sysfs_schemes_quota_goals>`.

+- ``update_schemes_tried_regions``: Update the DAMON-based operation scheme
+  action tried regions directory for each DAMON-based operation scheme of the
+  kdamond.  For details of the DAMON-based operation scheme action tried
+  regions directory, please refer to
+  :ref:`tried_regions section <sysfs_schemes_tried_regions>`.
+- ``update_schemes_tried_bytes``: Update only ``.../tried_regions/total_bytes``

+- ``clear_schemes_tried_regions``: Clear the DAMON-based operating scheme

 If the state is ``on``, reading ``pid`` shows the pid of the kdamond thread.
