I can only see it if I remove existing 
arch/arm64/boot/dts/intel/socfpga_agilex_socdk.dtb and then recompile with:
make -j24 DTC_FLAGS=-@ CHECK_DTBS=y intel/socfpga_agilex_socdk.dtb.

Toolchain:
aarch64-linux-gnu-gcc (Ubuntu 14.2.0-4ubuntu2~24.04) 14.2.0
aarch64-linux-gnu-gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0

Thanks.
