mm/damon/paddr: implement damon_folio_mkold()
damon_pa_mkold() receives physical address, get the folio covering the
address, and makes the folio as old. A following commit will reuse the
internal logic for marking a given folio as old. To avoid duplication of
the code, split the internal logic. Also, change the rmap walker
function's name from __damon_pa_mkold() to damon_folio_mkold_one(),
following the change of the caller's name and the naming rule that more
commonly used by other rmap walkers.
