[PATCH v2 00/11] Fixes and cleanups for the AD5686 IIO driver

[Rodrigo Alencar via B4 Relay <devnull+rodrigo.alencar.analog.com@kernel.org>]

This is the first series of three on updating the AD5686 driver.

A bigger patch series was sent before ("Extend device support for AD5686 driver"),
but this is not exactly a v2:

https://lore.kernel.org/r/20260422-ad5313r-iio-support-v1-0-ed7dca001d1b@analog.com

This one adds a number of cleanups and fixes, like:
- Refactor include headers (IWYU);
- Remove redundant register definition;
- Drop enum chip id in favor of per-device chip_info structs;
- Fix internal voltage reference control for single-channel devices;
- Acquire lock when doing power down control;
- Fix powerdown control for dual-channel devices;
