ALSA: aoa-soundbus: Switch to dev_pm_ops
Update the aoa-soundbus framework to use dev_pm_ops rather than the deprecated legacy suspend and resume callbacks. Since there isn't anything special to do at the bus level the bus driver does not have to implement any callbacks. The device driver core will automatically pick up and execute the device's PM ops. As there is only a single aoa-soundbus driver implementing suspend and resume, update both the core and driver at the same time to avoid unnecessary code churn.
