[PATCH 2/2] arm64: dts: amlogic: add libretech cottonwood support

From: Jerome Brunet
Date: Mon Oct 02 2023 - 10:10:46 EST

Add support for the Libretech cottonwood board family.
These 2 boards are based on the same PCB, with an RPi B form factor.

The "Alta" board uses an a311d while the "Solitude" variant uses an s905d3.
