[media] s5p-cec/st-cec: update TODOs

Update the TODOs explaining why these two drivers remain in
staging. The reason is that these drivers rely on userspace to
set the physical address, but that should come from the HDMI
output driver. This in turn needs the upcoming HDMI notifier
framework.

drivers/staging/media/s5p-cec/TODO

-This driver depends on the CEC framework, which is currently in
-staging, so therefor this driver is in staging as well.
+This driver requires that userspace sets the physical address.
+However, this should be passed on from the corresponding
+Samsung HDMI driver.
 
-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.
+We have to wait until the HDMI notifier framework has been merged
+in order to handle this gracefully, until that time this driver
+has to remain in staging.
