Affects machines akita, borzoi, connex, mainstone, spitz, terrier, tosa, verdex, and z2. In theory, a device becomes real only on realize. In practice, the transition from unreal to real is a fuzzy one. The work to make a device real can be spread between realize methods (fine), instance_init methods (wrong), and board code wiring up the device (fine as long as it effectively happens on realize). Depending on what exactly is done where, a device can work even when we neglect to realize it. This one appears to work. Nevertheless, it's a clear misuse of the interface. Even when it works today (more or less by chance), it can break tomorrow. Fix by realizing it right away.
