[PATCH v2 3/3] arm64: dts: qcom: ipq5018: add Ubiquiti UniFi U6 Enterprise

[Andrei-Alexandru Bleortu <me@andrei-z.com>]

The Ubiquiti UniFi U6 Enterprise is a ceiling-mount Wi-Fi 6E access point:

- SoC: Qualcomm IPQ5018
- RAM: 1 GiB
- Flash: SPI NOR (boot chain) and eMMC
- 5 GHz: QCN9074 on PCIe0
- 6 GHz: QCN9074 on PCIe1
- Ethernet: one 2.5GbE PoE port, a QCA8081 PHY behind GMAC1
- Accelerometer: ST LIS2DH12
- Button: reset

Describe what mainline supports today. The Ethernet port and the
IPQ5018's own 2.4 GHz radio are left out until the GMAC and the WCSS
remoteproc have bindings; the LED controller and the board MCU on the
I2C bus have none. The QCN9074s carry the calibration variants their
board data is looked up by. The SoC dtsi gains the pcie1_port0 label, as
pcie0 has, for the 6 GHz radio below that root port. The vendor QSEE
reserves 4 MiB, twice the SoC default.
