请求适配H618的PCDN板子。4+128G ，这块板子性价比不错。 #3434
Description
现在市面上H618有很多PCDN淘汰下来的二手盒子，这种盒子之前是用来跑PCDN的，现在咸鱼100左右一台，128G Emmc，H618的芯片，4G内存，2个USB接口，1个HDMI显示接口，1个千兆网口，没有WIFI配置，蓝牙不太清楚。可以用来做很多事了。
我在咸鱼买到的这款H618盒子是刷了定制的 18.04.6 LTS (GNU/Linux 5.4.125 aarch64) 这款系统 且 内置了PCDN捆绑。
目前适配的H618镜像：Orange Pi Zero3 ，我已经经过测试黑屏无法启动，DTB没有经过替换测试。
我测试了 https://github.com/NickAlilovic/build 的 Armbian-unofficial_25.05.0-trunk_Vontar-h618_bookworm_edge_6.12.11_server.img 镜像刷入后是可以正常开机的，但是网卡无法识别，该镜像我看只看DTB里面只启用了 ethernet@5030000 网卡（猜测可能是无线网卡），但这款盒子用的是 ethernet@5020000 网卡节点，我经过反编译DTB然后进行不断的调试，最终系统里面可以正常显示 eth0 网口，但是PHY出错了，我实在是找不到问题了，希望armbian能够适配该板子，在此进行感激各位开发者。
下面我附加一些DTB信息，希望能够有用：
目前 5.4 内核，可以正常使用千兆网卡的 DTB信息：
eth@5020000 {
compatible = "allwinner,sunxi-gmac";
reg = <0x00 0x5020000 0x00 0x10000 0x00 0x3000030 0x00 0x04>;

新的 6.12 内核，通过 Armbian-unofficial_25.05.0-trunk_Vontar-h618_bookworm_edge_6.12.11_server.img 进行反编译修改的DTB内核（该配置可以正常显示网口，但是会PHY失败，不知道什么问题）：
ethernet@5020000 {
compatible = "allwinner,sun50i-h616-emac", "allwinner,sun50i-a64-emac";
//compatible = "allwinner,sunxi-gmac";
