Audio: get_input_snd_device - use all bt sco devices for voice calls.

Use  AUDIO_DEVICE_OUT_BLUETOOTH_SCO
     AUDIO_DEVICE_OUT_BLUETOOTH_SCO_HEADSET and
     AUDIO_DEVICE_OUT_BLUETOOTH_SCO_CARKIT
and not only AUDIO_DEVICE_OUT_BLUETOOTH_SCO_HEADSET for voice calls.

Remove default voice_mic for sco devices - why we need default mic
for sco output devices if now we handle all sco output devices.
