audio: added support for dual mic capture

Added support for simultaneous capture of front and back mic.

Added device definitions for dual mic config for voice recognition use
case: no pre processing enabled.

stream->channels() reports actual channel mask instead of recontructing
it from channel count.

TODO: check if ACDB settings copied from single mic voice recognition
are correct.
