[PATCH RFC 6/6] arm64: dts: meson-gx: enable audin on odroidc2 platform

[Valerio Setti <vsetti@xxxxxxxxxxxx>]

This commit adds the TODDR #0 module to the Odroid-C2 platform.

Note: this not enough to be able to start recording data. An addiditional
dai-link node should be added with a reference to the external codec
being used. For example here's what should be added when an NXP SGTL5000
is used:

		dai-link-4 {
			sound-dai = <&audin CPU_I2S_DECODER>;
			dai-format = "i2s";
			mclk-fs = <256>;

			codec-0 {
				sound-dai = <&sgtl5000>;
			};
		};
