Expanding on this, the I2S port mappings for the APQ8016 should replace
the ones defined above with the constants you refer to in
dt-bindings/sound/apq8016.h:
MI2S_PRIMARY
MI2S_SECONDARY
etc.

Maybe defining a corresponding ipq806x.h in the same directory, and
moving the above definitions there?

As you pointed out i2s ports definitions can be moved to dt-bindings/soc/ipq806x.h but the channels can be directly defined in lpass-ipq806x.c as there would be no DT consumers for these defines anyway.
