[v2] 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.

v1 -> v2:
 * use 'linux_sunxi64' instead of default arch defconfig, which fixes
   ethernet networking (suggested by Sergey)
 * disabled rootfs.tar generation (suggested by Sergey)
 * increased ext2 fs size to 180M to fit more kernel modules
 * added DEVELOPERS entries for board files
