Upon second thought: the clock would only be used by the PM Domain
code.  So without a clocks property, "power-domains = <&cpg_clocks>"
would not make any sense, and the power-domains property should be
made optional.  The pinctrl and irqc also don't have it.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
