board: add Orangepi Zero3 support

Add initial support for Orangepi Zero3 board:
- U-Boot 2021.07 fork by Orangepi
- Linux 6.1.31 fork by Orangepi
- Default packages from buildroot

Enable CONFIG_MFD_AC200 as it is used directly by other module,
resulting in build failure when disabled.

Hello, Marcin Niestroj.
Networking does not work with this kernel configuration. I suggest using 
the "linux_sunxi64" configuration.

You need to replace the line:
> +BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_LINUX_KERNEL_DEFCONFIG="linux_sunxi64"

It is necessary to increase the size of the rootfs, because the kernel 
size has become larger:
> +BR2_TARGET_ROOTFS_EXT2_SIZE="120M"
BR2_TARGET_ROOTFS_EXT2_SIZE="200M"

You need to add this line to avoid creating a tar archive:
# BR2_TARGET_ROOTFS_TAR is not set

Thanks for suggestions! Applied them and already sent v2 of this patch.
