Subject: [PATCH] firmware: turris-mox-rwtm: make kobj_type structure
 constant

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.
