* XXX The line_out pin widget connection list may not be set to the

* to provide a best fit for pin/DAC configurations that are routable.
* For now, 927x DAC4 is not supported and 927x DAC1 output to ports
* A and B is not supported.
* Fill in the dac_nids table from the parsed pin configuration
* This function only works when every pin in line_out_pins[]
* contains atleast one DAC in its connection list. Some 92xx
* codecs are not connected directly to a DAC, such as the 9200
* and 9202/925x. For those, dac_nids[] must be hard-coded.
