There's struct of_node which is exactly that, though practically
speaking you need a device if you're going to bind automatically to
something from the device tree in a sensible fashion and there is actual
hardware under there so a device does make some sense.
This is in part compatibility with the existing Exynos code which uses
devices to probe the domains for non-DT systems.
