It seems marginally better to include "sc7180-lpass.h" to get this? I
don't really know the difference between the two but since unless
we're planning to delete the sc7180 version it seems like you might as
well include that one?

I'm an audio noob but isn't "MI2S_PRIMARY" something to be used with
"lpass_cpu", not with "alc5682" ?
I have no idea what the IDs correspond to on "alc5682". Are you sure
we even need an extra ID there? The "alc5682" bindings upstream don't
talk anything about dai-cells, but maybe they're just wrong...
