Yes, I know this.

I think I got it. ;-) You think that I'm not aware of that we _can_
use the device_type for matching the nodes. Well, I'm aware of it,
sure we can. ;-)

But we don't use it for the rtc nodes, and we don't want to encourage
the usage for the flat trees. And that's the point of this patch.
