This patch series refactors the DPF (Denoise Pre-Filter) parsing and 
nitialization
in the rkisp1 IPA module, and enables DPF tuning for the IMX219/OV5647/OV5640 
sensor.
The changes include restructuring the DPF configuration handling, improving
readability, and adding support for sensor-specific DPF parameters.
Support mode selection base on tuning parameters



Key changes:
- Inlined parseModes into parseConfig for cleaner initialization.
- Refactored mode lookup to use a string-to-int map, facilitating
  name-based lookup in tuning files.
- Introduced ActiveMode as an optional tuning parameter to set the
  default DPF state.
- Improved code structure in prepare() by using helper functions for
  enabled and disabled states.
- Enhanced debug logging for ISP parameter verification.
- Provided initial tuning data for IMX219, OV5640, and OV5647.


Changes since v9:
 - add registerControls to init context.ctrlMap[& controls::draft::NoiseReductionMode].
 - Change tuning config parser NoiseReductionMode from list to dictionary  and also update imx219/ov5647/ov5640 dpf config accordingly.
