[PATCH 0/2] Add support for Agilex5 SoCFPGA modular board

[niravkumarlaxmidas.rabara]

From: Niravkumar L Rabara <niravkumarlaxmidas.rabara@altera.com>

The Agilex5 Modular board consists of a compute module (Agilex5 SoCFPGA)
attached to a carrier board that provides PCIe and additional system
interfaces.

https://www.altera.com/products/devkit/a1jui0000061qabmaa/agilex-5-fpga-and-soc-e-series-modular-development-kit-es

* Patch 1 - Add compatible string for the modular board.
* Patch 2 - Add device tree for modular board.

Note: This patchset is based on socfpga maintainer's tree
