LoongArch: dts: Add I2S support to Loongson-2K1000 



The module is supported, adding it.

Not all Loongson-2K1000 boards have an i2s interface, here is an example
of enabling it:

sound {
	compatible = "loongson,ls-audio-card";
	model = "Loongson-ASoC";
	mclk-fs = <512>;

	cpu {
		sound-dai = <&i2s>;
	};

	codec {
		sound-dai = <&uda1342>;
	};
};

&apbdma2 {
	status = "okay";
};

&apbdma3 {
	status = "okay";
};

&i2c3 {
	status = "okay";

	pinctrl-0 = <&i2c1_pins_default>;
	pinctrl-names = "default";

	#address-cells = <1>;
	#size-cells = <0>;

	uda1342: codec@1a {
		compatible = "nxp,uda1342";
		reg = <0x1a>;
		#sound-dai-cells = <0>;
	};
};

&i2s {
	status = "okay";

	pinctrl-0 = <&hda_pins_default>;
	pinctrl-names = "default";
};
