staging: iio: light: iqs253: Fine tune settings
- Channel 0 to be used for stylus detection
- Channel 1 and 2 to be used for proximity detection
- Channel 0 should detect proximity at 0.5 cm
- Channel 1 and 2 should detect proximity at 2 cm
- SAR gpio to be pulled high on proximity detection else high
