ASoC: tlv320aic32x4: Implement resistors on input pins

The input pins of the aic3204 have resistors inline with them. The current code assumes that you want a 10k resistor inline with your inputs and implements it as a simple switch. 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. These pin settings are documented in TI's SLAA557 pages 135 and 136 (http://www.ti.com/lit/ml/slaa557/slaa557.pdf).

2013-05-13	staging: add mausezahn staging directory	Daniel Borkmann	1	-0/+128
	After some back and forth, we decided that it is easier to maintain mausezahn in a staging directory until it is fully reworked and cleaned up to be ready to be fully integrated. This way, it is better than having it in a separate branch, and we can also accept patches from outside more easily. Also, while at it, fix up some function mismatches with libcli.
