hal: Fix no audio during voice call with concurrent combo use case

-Music playback and voice use case uses snd device "voice-headphopne"
 as Rx device during active voice call, any new combo use case
 (camera shutter sound)gets routed to snd device "speaker" and 'headphone"
 during this state.
 When camera click sound is completed, it will end up disabling headphone
 device result in no audio on headphone for voice call.

 Add missing name to index conversion for voice-speaker and voice-headphone
 combo device to read required interface entry from audio platform
 info xml file.
