The firmware clocks driver was previously probed through a platform_device created by the firmware driver.
Since we will now have a node for that clocks driver, we need to create the device only in the case where there's no node for it already.

In the case you find a compatible device node you have to decrement the refcount of_get_compatible_child() increased before leaving.
