When an overlay contains a node related to a bus (i2c for instance) and its children nodes representing i2c devices, the flag is cleared for the bus node by the OF notifier but the "standard" probe sequence takes place (the same one is performed without an overlay) for the bus and children devices are created simply by walking the children DT nodes without clearing the FWNODE_FLAG_NOT_DEVICE flag for these devices. Clear the FWNODE_FLAG_NOT_DEVICE when the device is added, no matter if an overlay is used or not.
