Subject: [PATCH v2 4/4] arm64: dts: agilex5: initial support for Arrow
 AXE5-Eagle

The Arrow AXE5-Eagle is an Intel Agilex5 SoCFPGA based board with:

   - 1x PCIe Gen4.0 edge connector
   - 4-port USB HUB
   - 2x 1Gb Ethernet
   - microSD
   - HDMI output
   - 2x 10Gb SFP+ cages

As most devices aren't supported mainline yet, this is only the initial
support for the board.
