alsa: Add support for sound cards with 4-channel input.

Browse source 
Changes in v2:
 - Call the mapping a generic 4-channel input mapping
   instead of a 4-channel mic array mapping. The mapping
   will be used also by sound cards that have two stereo
   input jacks, so in those cases talking about mic arrays
   is wrong.
 - Added a comment about using the "hw" device name.
