configs: define sco sinks separately for msmnile

Usecase audio-playback-voip cannot be selected for device
AUDIO_DEVICE_OUT_BLUETOOTH_SCO because only combo device
AUDIO_DEVICE_OUT_ALL_SCO is defined in xml files so no
compatible direct output profile is found for device
AUDIO_DEVICE_OUT_BLUETOOTH_SCO.

Define SCO sinks separately for sources instead of combo
device.
