Correct it is not documented but it is at least used in Linux also by
drivers/gpio/gpio-mmio.c:810:	err = device_property_read_string(dev, "label", 
&label);

which is also not documented in DT binding.

I don't have a problem with it because I can't see it used anywhere.

But there are other devices where label is the part of binding. And IMHO this 
should be more generic property.

Thanks,
