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?
