[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.

Hi Conor,

ALINX is the brand of Xinyi Electronic Technology (Shanghai) Co., Ltd.
(芯驿电子科技（上海）有限公司), https://www.alinx.com/ - an FPGA/SoC
company and official partner of AMD Xilinx, Unisoc and Baidu.

The board is not in the alinx.com shop because ALINX describes EdgeBoard
as a customisation done for Baidu: Baidu owns the EdgeBoard brand and the
sales channel, while ALINX designs and manufactures the hardware. From
ALINX's own product documentation [1]:

"...as a Baidu AI partner, it has customized the Edgeboard series edge
  devices of the domestic AI flying paddle system for Baidu."

The FZ3A hardware manual and the schematics are authored by ALINX - the
manual cover carries the ALINX logo, www.alinx.com and the legal name
above, and every schematic sheet has the same ALINX title block.

Since ALINX is the hardware designer, I used "alinx" as the prefix
instead of "baidu". Happy to switch if you prefer the marketing brand.

[1] 
https://vd100-20232-v101.readthedocs.io/zh-cn/en/VD100_S1_RSTdocument_EN/00_aboutALINX_EN.html

For v3:
   - Fix the v2 description mistransliteration of the legal name:
       "^alinx,.*":
         description: Xinyi Electronic Technology (Shanghai) Co., Ltd. 
(ALINX)
   - Put the website URL in the commit message.

Thanks for the ack on patch 2/3, I will carry it into v3.

Best regards,
Pufan Jin
