Why would you want to instantiate devices that you cannot address at all anyway? The only driver that can know what to do with the device node is the driver for the device that has the phandle reference to it; it can instantiate it.
It's not a single device referencing it, it's multiple devices referencing it, and we can do useful things even with no external references at all. The node itself is a real thing that we can point at and control (using GPIOs or something similar).
