iio: Add sensor wake_up support

- Add wake_up sensor type support.
- Remove IIO dependencies from light and proximity headers for portability.
- Add driver documentation.
- Add ICM20628 compatibility label.
- Add global disable allowing no driver interaction with device.
- Fix interpolation 64-bit divide in light and proximity modules.
- Fix CM32180 device parameter table.
- Fix IQS2X6 Kconfig label.
