[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).
