Docs/mm/damon/design: update for DAMOS_QUOTA_NODE_ELIGIBLE_MEM_BP

Browse Source 
Patch series "mm/damon: update, optimize, and clean up doc, tests, and
code".

Patches 1 and 2 update the design and ABI documents for recently added
DAMON features.  Patches 3-7 add or update more unit and self tests for
DAMON to cover recently changed or added functions and sysfs files.  Patch
8 optimizes damon_commit_target_regions() to skip unnecessary adjacent
ranges setup.  Patches 9-11 clean and fix up recently added DAMON sysfs
interface code for readability.


This patch (of 11):

Commit 9138e27a3b ("mm/damon: add node_eligible_mem_bp goal metric")
introduced DAMOS_QUOTA_NODE_ELIGIBLE_MEM_BP but forgot updating the DAMON
design document for that.  Update.
