PS1, Line 70: 	if (!fw_config_probe(FW_CONFIG(WIFI_TYPE, WIFI_CNVI))) {
> It will cause boot fail with "ASSERTION ERROR:file `src/soc/intel/alderlake/fsp_params.c`, line 820", seem like CB:83148.
> When fw_config is unprovisioned (CNVi WIFI is disabled), CNVi BT must be turned off. Thanks.

What if FW config doesn't exist and we are coming here to probe?
