[PATCH] mm/damon/sysfs: make more kobj_type structures constant

[Thomas Weißschuh]

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.
