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