* Update rk3588-orangepi-5-ultra.dts
While I don't fully understand either the `kernel-dtb` command nor the dt syntax itself for some reason the `nophandles` version stripped more than actually phandles. Lets see what happens this way.

Change with command:
sed -i "/CONFIG_OPTEE/d" patch/u-boot/legacy/u-boot-radxa-rk35xx/defconfig/*
- in main `rockchip64` family, for current/edge (6.6 / 6.11)
- using mainline u-boot's generic rk3568 for current/edge
- vendor kernel is added via a copypasta hook to piggyback on `rk35xx`
- requires armbian/linux-rockchip PR https://github.com/armbian/linux-rockchip/pull/245
- vendor u-boot:
- is required to bringup npu for vendor kernel (otherwise panics)
- .dts done based on vendor kernel DT + looking at armsom-sige3
- defconfig ripped off from armsom-sige3
- rebased 2 patches
- moved null patches for dts & defconfigs to `dt` / `defconfig` dirs
- rename defconfigs since we're at it; use board-specific only
- defconfigs re-saved
- rebased 3 patches
- moved null patches for dts & defconfigs to `dt` / `defconfig` dirs
- don't rename defconfigs: those are shared with Joshua Riek (ubuntu-rockchip)
- defconfigs re-saved
