mm/damon/sysfs: make more kobj_type structures constant 

Since commit ee6d3dd4 ("driver core: make kobj_type constant.") the
driver core allows the usage of const struct kobj_type.

Take advantage of this to constify the structure definition to prevent
modification at runtime.

These structures were not constified in commit e56397e8
("mm/damon/sysfs: make kobj_type structures constant") as they didn't
exist when that patch was written.
