If my understanding was correct, I think I can't.
In below case, "sound_soc" has its *dev, but "cpu" and "codec" doesn't
have *dev, it has node only. Thus, we are using of_clk_get() for these now.

        clk = of_clk_get(cpu, xxx);
        clk = of_clk_get(codec, xxx);

        sound_soc {
                ...
                cpu {
                        ...
=>                      clocks = <&xxx>;
                };
                codec {
                        ...
=>                      clocks = <&xxx>;
                };
        };
