of: Add .of suffix to device names from devicetreestable/v2018.12
Previous implementation used to add a number to the device names for devices registered from the device tree which did not have a 'reg' property, thus a device node named "state" resulted in a device name "state.<x>". Current implementation skips that number and we get a device named "state". This conflicts with our barebox state implementation which tries to register a device named "state" itself. We could rename the state device nodes of all our device trees, but it causes less trouble to rename the devices. This adds a ".of" suffix to the device names for devices registered from the device tree which also has the nice effect that they now can easily be recognized.
