Improve charger detection in usbpd_check_cp_psy

- Added a list of charger names to support multiple charger types.
- Implemented a retry mechanism to handle cases where the charger is not yet registered.
- Added detailed debug logs to track charger search and detection.
- Improved error handling and fallback mechanism.
