[PATCH 05/10] ARM: socfpga: add Arrow AXE5 Agilex5 board

[Steffen Trumtrar <s.trumtrar@pengutronix.de>]

Add the Agilex5-based Arrow AXE5-Eagle board.
It consists among other things of:
  - Agilex5 SoCFPGA
  - 1 GB LPDDR4 SDRAM for HPS
  - 1 GB LPDDR4 SDRAM for FPGA
  - 1 Gb QSPI for configuration via SDM
  - microSD
  - 4-port USB hub
  - 2x 1Gb Ethernet
  - HDMI output
