Hi Frank,

There are two main points:

1. The SOM dtsi is intended to be reused with different carriers.
   Defining the LEDs there forces every carrier to inherit the reference
   board’s LED configuration. Customers then have to override those
   definitions or explicitly delete the LED nodes if their carrier has no LEDs.
   Keeping the definitions in the carrier DTS avoids requiring customers
   to undo configuration for hardware that is not part of the SoM.

2. The Ethernet connectors, LEDs and their wiring are on the carrier.
   Their definitions therefore belong in the carrier DTS, while the SOM dtsi
   should describe the hardware on the module.
   This change makes that separation consistent across our boards.

There is no functional change for the existing Symphony and Sonata boards:
their final device trees retain the same LED configuration.

Thank you Frank,
Best Regards,
Stefano
