[PATCH v6 3/3] arm64: dts: rockchip: Add Orange Pi 5 Pro board support

[dennis@ausil.us]

From: Dennis Gilmore <dennis@ausil.us>

Add device tree for the Xunlong Orange Pi 5 Pro (RK3588S).

- eMMC module, you can optionally solder a SPI NOR in place and turn
 off the eMMC
- PCIe-attached NIC (pcie2x1l1)
- PCIe NVMe slot (pcie2x1l2)
- AP6256 WiFi (BCM43456) via SDIO with mmc-pwrseq
- BCM4345C5 Bluetooth
- es8388 audio
- USB 2.0 and USB 3.0
- Two HDMI ports, the second is connected to the SoC's DP controller
  driven by a transparent LT8711UXD bridge that has firmware onboard and
  needs no node defined.

Vendors description and links to schematics available:
