If you want to support "DAMON_DBGFS" in config file, it only depends on
any one of "DAMON_VADDR" and "DAMON_PADDR", and sometimes we just want to
use damon virtual address function, but it is unreasonable to include
"DAMON_PADDR" in config file which cause the damon/paddr.c be compiled.
So there just do little change to fix it.

This builds the debugfs interface for DAMON. The user space admins
can use the interface for arbitrary data access monitoring.
