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

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

The Linux DTS is already accepted upstream and will be part of Linux
6.5:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts?id=de2bdfb7f79d5c655eb056d459e02be2c7f13c8b

The U-Boot DTS and defconfig have been submitted:
