[PATCH] of: Add .of suffix to device names from devicetree

[Sascha Hauer <s.hauer@pengutronix.de>]

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.

Fixes: 7e497d48acbd11 ("of: Port latest of_device_make_bus_id() implementation")
