[PATCH v2 3/3] arm64: zynqmp: Add ALINX EdgeBoard FZ3A

[Pufan Jin]

Add device tree for the ALINX EdgeBoard FZ3A, a single board computer
based on the Xilinx Zynq UltraScale+ XCZU3EG SoC.

Supported peripherals:
  - UART1 debug console
  - eMMC (HS200) and microSD card
  - GEM3 Ethernet with Micrel KSZ9031 PHY on the MDIO bus
  - I2C0 and I2C1
  - QSPI NOR flash
  - PCIe
  - USB 3.0 host
  - DisplayPort output

Tested on hardware with Linux 7.3.0-rc5: the board boots from SD card
into userspace over the serial console, gem3 negotiates 1000Mbps/Full
duplex with phy-mode = "rgmii-id", and the eMMC runs in HS200 mode.

The base DTB passes CHECK_DTBS=y, and the Xilinx SoC binding passes
dt_binding_check.
