Subject: [PATCH v2 0/4] Add support for ADAQ776x-1 ADC Family

This adds support for the ADAQ7767-1, ADAQ7768-1 and ADAQ7769-1 devices. 

The ADAQ7768-1 and ADAQ7769-1 integrate a programmable gain amplifier (PGA)
with 7 and 8 gain options, respectively. The ADAQ7767-1 and ADAQ7769-1 
also feature a 3-pin selectable Anti-aliasing filter (AAF) gain.

Changes in v2:
* adi,aaf-gain property renamed to adi,gain-milli. Default value added.
* fixed some commit messages. 
* Added 'select RATIONAL' to Kconfig.
* Added lock to protect PGA value access.
* rewrote AAF gain check and replaced error returns with warnings.
* Addressed other review comments, see individual patches.
* Link to v1: https://lore.kernel.org/linux-iio/cover.1754617360.git.Jonathan.Santos@analog.com/T/#t
