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.
