AC'97 codecs don't typically have an I2C connection (if ever).
You shouldn't have two device nodes for the same device if ever you
can help it; instead, have the device's sole device node contain a
property that points to the device node of its secondary bus. That
property could be called "i2s-handle" for a standard codec (which
probably is a direct child of an IIC bus, itself).
