BALATON Zoltan eb604411a7 hw/audio/via-ac97: Basic implementation of audio playback
Add basic implementation of the AC'97 sound part used in VIA south
bridge chips. Not all features of the device is emulated, only one
playback channel is supported for now but this is enough to get sound
output from some guests using this device on pegasos2.
