mm/damon: rename CONFIG_DAMON_DBGFS to DAMON_DBGFS_DEPRECATED
DAMON debugfs interface is deprecated. The fact has documented by commit
5445fcbc4cda ("Docs/admin-guide/mm/damon/usage: add DAMON debugfs
interface deprecation notice"). Commit 620932cd2852 ("mm/damon/dbgfs:
print DAMON debugfs interface deprecation message") further started
printing a warning message when users still use it. Many people don't
read documentation or kernel log, though.
Make the deprecation harder to be ignored using the approach of commit
eb07c4f39c3e ("mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED").
'make oldconfig' with 'CONFIG_DAMON_DBGFS=y' will get a new prompt with
the explicit deprecation notice on the name. 'make olddefconfig' with
'CONFIG_DAMON_DBGFS=y' will result in not building DAMON debugfs
interface. If there is a real user of DAMON debugfs interface, they will
complain the change to the builder.
