Is there an established Linux convention for expressing that dual-parent
relationship for I2C?  The phandle schemes for cross-tree gpio, clk, and
interrupt relationships obviously bear some resemblance to the problem,
but I haven't seen anything for I2C.

Yes. Place the codec under the i2c controller and use a tope level audio
complex node with phandles to both the codec and i2s nodes.

The nVidia bindings are probably the best ones to look at as an example
here.
