[port request] Please add support for Firefly ITX-3588J

[BillFleming]

Have the model with nice big fat 32GB RAM ready to test. https://en.t-firefly.com/product/industry/itx3588j https://en.t-firefly.com/doc/download/page/id/139.html

Also have 1.8V ttl hooked up for debugging. As long as we don't try to run graphics in towboot uart will work ok. Current graphics will crash chip and corrupt uart (lol) so we want headlines like on PinePhone Pro.

This is mostly blocked on RK3588 support with upstream U-Boot, but there's been progress.

One thing that may take some time is display init, but I'm just guessing.

Once RK3588 somewhat works, it will be possible to start thinking about all those boards, including ITX-3588J.
