  To: buildroot

Add a defconfig for ICnova A20 SomPi compute module on ADB4006
development board with Allwinner A20 chip and 512MB/1GB RAM.

Board support package includes the following components:
- mainline Linux kernel 6.1.35
- mainline U-Boot 2023.04
- custom dts & uboot defconfig
- default packages from buildoot

https://wiki.in-circuit.de/index.php5?title=ICnova_ADB4006
https://wiki.in-circuit.de/index.php5?title=ICnova_A20_SODIMM

changes in v2:
- rebase on 2023.05
- get dts reviewed on the linux mailing list and
scheduled for kernel 6.5 [1]
- uboot defconfig upstreaming in progress [2]
