[PATCH v2 0/3] iio: adc: stm32: Add support for differential channels

Add support for differential channels that can be found on STM32H7 ADC:
- Introduce new DT property 'st,adc-diff-channels'.
- Slightly rework single-ended channels definition in stm32-adc driver.
- Add support for differential channels to stm32-adc driver.

---
Changes in v2:
- Add an example and a note in dt-bindings to better explain
 'st,adc-diff-channels' usage (based on Jonathan & Rob remarks).
- Update variable names in stm32_adc_chan_init_one() based on Jonathan remark.
