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

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 at 21`, `usb-typec at 67`,
          `pmic at 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).
