Docs/admin-guide/mm/damon/usage: use sysfs interface for tracepoints example
Patch series "mm/damon: make DAMON debugfs interface deprecation unignorable". DAMON debugfs interface is deprecated in February 2023, by commit 5445fcbc4cda ("Docs/admin-guide/mm/damon/usage: add DAMON debugfs interface deprecation notice"). Make the fact unable to be easily ignored by removing an example usage from the document (patch 1), renaming the config (patch 2), adding a deprecation notice file to the debugfs directory (patches 3-5), and renaming the debugfs file that essnetial to be used for real use of DAMON (patches 6-9). This patch (of 9): DAMON tracepoints example on the DAMON usage document is using DAMON debugfs interface, which is deprecated. Use its alternative, DAMON sysfs interface.

While the monitoring is turned on, you could record the tracepoint events and
show results using tracepoint supporting tools like ``perf``. For example::

# sleep 5
# kill 9 $(pidof perf)
