The current LE audio offload capabilities is hardcode in the
Bluetooth audio HAL. It has the limitation that all the project
would expose the same capabilities. As the newer project comes,
if the ADSP or the controller could handle more configuration
with higher quality or higher bandwidth. It would impact older
project may not work on it. So we plan the feature to make the
le audio offload support to be more flexible.
