Rather than silently updating the config silently, what do you think about asserting if the mainboard has set the wrong config. That way it should ensure that the mainboard developer fixes the devicetree config.

```
params->CnviMode = is_dev_enabled(dev);
params->CnviBtCore = config->CnviBtCore;
params->CnviBtAudioOffload = config->CnviBtAudioOffload;

/* Assert if CNVi BT is enabled without CNVi being enabled. */
assert(params->CnviMode || !params->CnviBtCore);
/* Assert if CNVi BT offload is enabled without CNVi BT being enabled. */
assert(params->CnviBtCore || !params->CnviBtAudioOffload);
```
