orangepi3b: switch to Kwiboo's 23.10(-rc4) u-boot, plus patches

> Based on AmazingFate's kernel DT and Kwiboo's `rk3568-2023.10`

Tested with a OrangePi 3B 4GB v1.1:
- SD-card boot
- eMMC boot
- SPI Flash boot
  - chip is XMC `XM25QU128CWIQ`, not `W25Q256JWEIQ` listed in schematics
- PCIe/NVMe
- Ethernet has stable MAC
- can boot both edge (mainline) and legacy (vendor rk 5.10) kernels

- USB in uboot is untested
- UMS untested (I lost my A-to-A otg cable)
