After another thought about your "one line" node, I think this can be even
improved, so that :
 - uart clocks are put into pxa2xx.dtsi instead of pxa27x.dtsi
 - replace all pxa2xx_clks by clks
 - let pxa27x.dtsi, pxa3xx.dtsi declare the clks label

This way we'll have :
 - pxa2xx.dtsi
		ffuart: uart@...00000 {
                        compatible = ...
                        ...
			clocks = <&clks CLK_FFUART>;
		};
 - pxa27x.dtsi
                clks: pxa2xx_clks@...00004 {
                        compatible = "marvell,pxa270-clocks";
                        #clock-cells = <1>;
                        status = "okay";
                };
 - pxa3xx.dtsi
                clks: pxa3xx_clks@...00004 {
                        compatible = "marvell,pxa300-clocks";
                        #clock-cells = <1>;
                        status = "okay";
                };

Cheers.
