This callback function was only being used in A2DP sink. Since we do not
expect system/bt to inform the audio focus state upwards we do not need
this callback.

- Add interface to report audio focus change from Bluetooth Apk

Both use the same structs for APIs and callbacks, but now
source and sink mode can operate independently with separate
Bluetooth profile services in the framework.
An extra callback btav_audio_config_callback is used for reporting
audio configuration for A2DP sink role
