[PATCH 2/2] arm64: dts: socfpga: agilex7-gen2: Add initial device tree

[muhammad . nazim . amirul . nazle . asmade]

From: Nazim Amirul <muhammad.nazim.amirul.nazle.asmade@xxxxxxxxxx>

Add initial device tree support for the Intel SoCFPGA Agilex7 Gen2
platform. This introduces the SoC DTSI and the SoCDK board DTS as
the first upstream submission for this platform.

The Agilex7 Gen2 SoC features a heterogeneous CPU cluster with
Cortex-A520 and Cortex-A720 cores, and includes an SMMU v3 for
memory management.
