Bluetooth: btrtl: Avoid loading the config file on security chips
For chips with security enabled, it's only possible to load firmware
with a valid signature pattern.
If key_id is not zero, it indicates a security chip, and the driver will
not load the config file.
- Example log for a security chip.
