Drop the N5X board-local CFG_EXTRA_ENV_SETTINGS override and use the
common SoC64 environment from socfpga_soc64_common.h, matching other
SoC64 boards.
Do not enable CONFIG_DISTRO_DEFAULTS. N5X continues to use the legacy
common env helpers referenced by BOOTCOMMAND (fatscript and mmc* /
mmcfit*) with a board u-boot.scr that only enables the FPGA bridges,
which matches the current N5X SD image layout.
Also set CONFIG_SYS_LOAD_ADDR=0x02000000, matching Agilex/S10, so kernel
and FIT loads sit above the 32 MiB /reserved-memory svcbuffer at 0x0 in
socfpga_agilex.dtsi (included by the N5X board DT). Drop
CONFIG_SYS_BOOTM_LEN=0x2000000 so the ARM64 default (128 MiB) applies;
the previous 32 MiB override is too small for current images.
Tested-on: Intel SoCFPGA N5X SoCDK hardware (ddr retention, linux boot).

Note: This patch depends on the concurrent N5X platform support series:
https://patchwork.ozlabs.org/project/uboot/cover/[email protected]/
That series makes ATF/FIT the default (BOOTCOMMAND uses mmcfitload/
mmcfitboot), so fdt_addr is no longer used by the supported boot path.
Aligning fdt_addr with common SoC64 (0x08000000) therefore does not
change the FIT flow.
