mm/damon/paddr,vaddr: remove damon_{p,v}a_{target_valid,set_operations}()

Because DAMON debugfs interface and DAMON-based proactive reclaim are now
using monitoring operations via registration mechanism,
damon_{p,v}a_{target_valid,set_operations}() functions have no user.  This
commit clean them up.
