Ludwig Kormann f47b5e39fb configs/icnova-a20-adb4006: new defconfig
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
