At present this function is never called when of-platdata is enabled since we never have a device tree. However, this function is responsible for copying over the of-platdata, so we must call it. Otherwise the probe() method would have to be used. Correct this and fix the sandbox serial driver to not read from the device tree and try to write to what is read-only platdata on some platforms.
