Camera Initialization Fails with DFS Enabled on ESP32-S3 #799
Description
Checklist
- Checked the issue tracker for similar issues to ensure this is not a duplicate
- Read the documentation to confirm the issue is not addressed there and your configuration is set correctly
- Tested with the latest version to ensure the issue hasn't been fixed

Expected behavior
The camera should initialize successfully with DFS enabled, as it does on the ESP32.
Actual behavior (suspected bug)
Enabling Dynamic Frequency Scaling (DFS) on the ESP32-S3 causes the esp_camera component to fail during initialization. The same configuration works correctly on the ESP32.
Camera model OV2640.
