ALSA: hda - Fix initial capture source connections of ALC880/260
The widget connections of ADC of ALC880 and ALC2260 aren't initialized, thus it might point to invalid pin. This can be a problem when mode=auto and there is only one input pin. Then user can't change the connection at all. This patch adds the code to initialize the input pin connection of these codecs.
