[media] media/core: Replace ctrl_class with which
Replace the obsolete field ctrl_class with "which".
Make sure it not used in future modules by commenting out the field with
ifndef __KERNEL_ .
The field cannot be simply removed because that would be change on the
kenel API to the userspace (and we don't like that).
