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.
