The Orange Pi 5 Ultra is another board in the Orange Pi 5 family.

Orange Pi 5 Ultra uses Rockchip RK3588,
a new generation of octa-core 64-bit ARM processor,
which includes quad-core A76 and quad-core A55.

Features tested on a Orange Pi 5 Ultra 16GB:
- SD-card boot
- eMMC boot

The Xunlong Orange Pi 3B is a single-board computer based on the
Rockchip RK3566 SoC.

The two hw revisions use different io-voltage for Ethernet PHY and can
be identified using GPIO4_C4:
- v1.1.1: x (internal pull-down)
- v2.1:   PHY_RESET (external pull-up)

Implement rk_board_late_init() to set correct fdtfile env var and
board_fit_config_name_match() to load correct FIT config based on what
board is detected at runtime so a single board target can be used for
both hw revisions.

Minimal DTs that includ DT from dts/upstream is added to support booting
from both hw revision and only set Ethernet PHY io-voltage when the hw
revision is detected at runtime. A side-affect of this is that defconfig
show OF_UPSTREAM=n, however dts/upstream DTs is used for this board.

Features tested on Orange Pi 3B 4GB (v1.1.1 and v2.1):
- SD-card boot
- eMMC boot
- SPI Flash boot
- Ethernet
- PCIe/NVMe
- USB host
