Please change "MI2S_PRIMARY" to "0". "MI2S_PRIMARY" is a numbering
system for "lpass_cpu" not for "alc5682". I'm not aware of symbolic
names for the alc5682's DAIs.

>From digging through the code and testing, it appears that for alc5682:
0 - aif1
1 - aif2

Thus you could be a little more documenting by doing:

sound-dai = <&alc5682 0 /*aif1*/>;
