Subject: Docs/mm/damon/index: mention DAMOS on the intro
Date: Tue, 10 Jan 2023 19:03:55 +0000

What DAMON aims to do is not only access monitoring but efficient and
effective access-aware system operations.  And DAMon-based Operation
Schemes (DAMOS) is the important feature of DAMON for the goal.  Make the
intro of DAMON documentation to emphasize the goal and mention DAMOS.
