[Test Case]
1. Boot up the machine of new Dell Intel PantherLake platform with CirrusLogic CS42L43 + new amplifiers
2. Open settings->Sound->Output Device and make sure it's not Dummy audio devices
3. Click test icon for basic audio output functions
4. Use `arecord` to record and play the recorded audio file with `aplay` for basic speaker/microphone functions.
[Where problems could occur]
It adds the support for new CirrusLogic codec+amplifier on PTL platform. No regression expected at the current stage.
