[PATCH v3.1 02/46] media: mc-entity: Rename media_entity_remote_pad() to media_pad_remote_pad_first()

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

The media_entity_remote_pad() is misnamed, as it operates on a pad and
not an entity. Rename it to media_pad_remote_pad_first() to clarify its
behaviour.
