[media] s5p-cec/TODO: add TODO item

Mention that the HDMI driver should pass on the physical address
to this driver, rather than requiring userspace to do this.

drivers/staging/media/s5p-cec/TODO

-There's nothing wrong on this driver, except that it depends on
-the media staging core, that it is currently at staging. So,
-this should be kept here while the core is not promoted.
+This driver depends on the CEC framework, which is currently in
+staging, so therefor this driver is in staging as well.
+
+In addition, this driver requires that userspace sets the physical
+address. However, this should be passed on from the corresponding
+samsung HDMI driver. It is very annoying if userspace has to do this,
+and other than USB CEC adapters this must be handled automatically.
