This patch series refactors and enhances the DPF ( Pre-Filter Denoise) handling
in the rkisp1 IPA. It includes:

- Add exposure index computation helpers
- Initialize DPF tuning configuration
- Define IPA control block for DPF
- Add support for reduction modes in DPF
- Collect manual DPF overrides
- Detect DPF device overrides
- Manage DPF mode transitions
- Apply DPF overrides
- Refactor DPF prepare flow
- Expose DPF control map
- Publish DPF metadata

This series improves maintainability, adds flexibility for DPF tuning, and
ensures correct override handling.
