rk3188 only has one i2s controller, so this should be i2s0

As stated above, rk3188 only has one i2s controller at all, so this block of 
the 3 i2s controllers should move to rk3066a.dtsi and rk3188.dtsi should get 
its own, like

+	i2s0: i2s at 1011a000 {
+		compatible = "rockchip,rk3066-i2s";
+		reg = <0x1011a000 0x2000>;
+		interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		dmas = <&dmac1_s 6>, <&dmac1_s 7>;
+		dma-names = "tx", "rx";
+		clock-names = "i2s_hclk", "i2s_clk";
+		clocks = <&cru HCLK_I2S0>, <&cru SCLK_I2S0>;
+		status = "disabled";
+	};

Especially as the clock for the one i2s controller of the rk3188 is of course 
labeled xCLK_I2S0.

Also, please sort device nodes by their address when adding them to the dtsi 
files.


Thanks
Heiko
