Current simple-card is supporting this style for clocks

	sound {
		...
		simple-audio-card,cpu {
			sound-dai = <&xxx>;
			clocks = <&cpu_clock>;
		};
		simple-audio-card,codec {
			sound-dai = <&xxx>;
			clocks = <&codec_clock>;
		};
	};

Now, it can support this style too, because we can use
devm_get_clk_from_child() now.

	sound {
		...
		clocks = <&cpu_clock>, <&codec_clock>;
		clock-names = "cpu", "codec";
		clock-ranges;
		...
		simple-audio-card,cpu {
			sound-dai = <&xxx>;
		};
		simple-audio-card,codec {
			sound-dai = <&xxx>;
		};
	};

I don't see any reason why we need this patch though. The binding
works as is, so supporting different styles doesn't seem like a
good idea to me. Let's just keep what we have? Even if a sub-node
like cpu or codec gets more than one element in the clocks list
property, we can make that work by passing a clock-name then
based on some sort of other knowledge.
