[PATCH] mm/damon: update expired description of damos_action

[Sang-Heon Jeon <ekffu200098@gmail.com>]

Nowadays, damos operation actions support more various operation set.
But comments(also, generated documentation) doesn't updated.
So, fix the comments with current support status.

I also found below patch(https://lore.kernel.org/damon/20250730200239.60984-1-sj@kernel.org/T/#t)
So, Is it means that DAMOS_STAT is only supported by paddr now?
If my understanding is correct, then we need to fix Design documentation
and comments both.

However, since it will be fixed soon. Keeping current status is also
affordable. So could you check this point as well?
