[media] media-device: export the entity function via new ioctl
Now that entities have a main function, expose it via MEDIA_IOC_G_TOPOLOGY ioctl. Please notice that some entities may have secundary functions. Such use case will be addressed later, when we add support for the Media Controller properties.
