Subject: Docs/mm/damon: move DAMON operation sets list from the usage to the design document
Date: Fri, 16 Feb 2024 16:58:40 -0800
The list of DAMON operation sets and their explanation, which may better
to be on design document, is written on the usage document. Move the
detail to design document and make the usage document only reference the
design document.
