Since commit ee6d3dd4ed48 ("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 e56397e8c40d ("mm/damon/sysfs: make kobj_type structures constant") as they didn't exist when that patch was written.
