core: platform: add warning if driver has no owner
Commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register") introduced a codepath which could result into drivers having no owner. This went unnoticed for months, so add a warning in case this happens again somewhere else somewhen.
