devm_of_clk_add_hw_provider() expects, as the "_of_" string indicates,
a non NULL dev->of_node, otherwise it will return -ENODEV.
Since this driver can be probed either through the old-fashioned
platform device registration or through a DT node that is a child of the
firmware node, call devm_of_clk_add_hw_provider() only when the DT node
is present.
