Add initial support for TechNexion EDM-G-IMX8M-PLUS SOM and WB-EDM-G
carrier board.

Changes in v4:
- Incorporate review feedback from Shawn and apply further cleanups to DTS
  style and node naming.

in patch 2/2:
       - Addressed formatting issues by adding newlines and removing
         unnecessary backslashes.

       - Removed the lvds-backlight node for the optional display panel,
         which will be handled by a device tree overlay.

       - Aligned several node names with DT conventions. For example:
         - `codec@1a` -> `audio-codec@1a`
         - `gpio-leds` -> `leds`
         - `pcie0-refclk` -> `clock-pcie-ref`
         - `wlreg-on` -> `regulator-wl-reg-on`

Changes in v3:
- The changes address DT schema warnings, remove unused regulators, and
  improve the overall structure.

in patch 2/2:
       - Fixed DT Schema Warnings: Renamed the i2c-gpio node to i2c-0 to
         resolve a naming convention warning reported by Rob's checker.

       - Removed Unused Regulators: Removed several unused regulator-fixed
         nodes for LVDS, backlight, ethernet power, and the OTG VBUS, as
         pointed out by Peng Fan.

       - Added EEPROM Nodes: Added device tree nodes for the EEPROMs
         present on both the SOM and the baseboard.

       - Node Reorganization: Relocated the iomuxc node to the end of the
         device tree files for better readability.

Change in V2:
- Ensured accurate `To:` and `Cc:` addresses by utilizing
  `b4 prep --auto-to-cc`. (Thanks to Krzysztof Kozlowski for the
  tip on this command and helpful suggestion from Rob Herring).

in patch 1/2:
        - Add Acked-by tag.

in patch 2/2:
        - Generic Node Naming: Refactored device tree node names for I2C
          GPIO expanders, the USB Type-C controller, and the PMIC to adhere
          to generic naming conventions (e.g., `gpio@21`, `usb-typec@67`,
          `pmic@25`).

        - Removed Unused SPI Node: Eliminated the `spidev1` node due to an
          incorrect and non-existent compatible string (`rohm,dh2228fv`).

        - Minor formatting improvements (e.g., whitespace, indentation).

Hi Shawn,

This is just a gentle ping to follow up on this patch series, in case it got buried in other emails.

Thanks, 

Richard
