[PATCH v4 0/3] Add support for Variscite DART-MX91 and Sonata board

[Stefano Radaelli <stefano.radaelli21@gmail.com>]

This patch series adds support for the Variscite DART-MX91 system on
module and the Sonata carrier board.

The series includes:
- Device tree bindings documentation for both SOM and carrier board
- SOM device tree with on-module peripherals
- Sonata carrier board device tree with board-specific features

The implementation follows the standard SOM + carrier board pattern
where the SOM dtsi contains only peripherals mounted on the module,
while carrier-specific interfaces are enabled in the board dts.

v3->v4:
 - Fix space between BUCK4/BUCK5 aned parenthesis
 - Remove unused pinctrl groups

v2->v3:
 - Rebased the series to fix DTS apply issues.

v1->v2:
 - Ordering by hex and node name.
