    [media] v4l2-subdev: use MEDIA_ENT_T_UNKNOWN for new subdevs

    Instead of abusing MEDIA_ENT_T_V4L2_SUBDEV, initialize
    new subdev entities as MEDIA_ENT_T_UNKNOWN.

that added a warning to media controller core code without updating drivers to comply with the new requirements.

The warning is harmless, drivers will eventually be updated.
