This patch enables those routings within the driver to provide more flexibility for different board configurations. These settings are documented on pages 135 and 136 of TI's SLAA557 document available at http://www.ti.com/lit/ml/slaa557/slaa557.pdf. This patch might introduce some breakage for current users because it changes some mixer routing settings from a straight switch to an enum for the different resistor values instead. I'm not sure there's anything we can do in code to mitigate these effects, but am open to requests for changes if there's something I'm not aware of.

This patch creates an enum for each pin and allows you to switch between not connected, 10k, 20k and 40k ohm values. This more closely models the acutal aic3204 part.
