When hardware design introduces significant sensor data noise,
performance can be improved by adjusting register settings.

Changes in v3:
- Removed global register block configuration:
  - Replaced global tuning blob with individual properties for each configurable setting.
- New properties added for individual configurations:
  - tyhx,odr: Added scanning period configuration.
  - tyhx,range: Full-scale range configuration for each channel.
  - tyhx,avg: ADC averaging number configuration for each channel.
  - tyhx,osr: Oversampling rate configuration for each channel.
  - tyhx,sample-num: ADC sample frequency configuration.
  - tyhx,integration-num: Integration number configuration.
  - tyhx,lp-alpha: Low-pass filter coefficient configuration for each channel.
  - tyhx,bl-up-alpha: Baseline filter up coefficient configuration.
  - tyhx,bl-down-alpha: Baseline filter down coefficient configuration.
  - tyhx,drdy-interrupt: Added interrupt function enable configuration.
  - tyhx,int-high-num: Proximity persistency number (Near).
  - tyhx,int-low-num: Proximity persistency number (Far).
- General improvements:
  - Improved description clarity for all properties.
  - Updated examples section for better clarity and accuracy based on new properties.
- Parsing functions added:
  - Implemented parsing functions for the newly added properties.

Changes in v2:
- In the YAML file, boundary constraints have been applied to the `tyhx,performance-tuning` property, requiring the number of elements to be between 2 and 512. The description also informs users that the number of elements must be a multiple of 2.
- In the function implementation, boundary checks have been added for this property, ensuring that the number of elements is even.
