[PATCH] armv8: spl: Fix build with LINUX_KERNEL_IMAGE_HEADER

[Alper Nebi Yasak]

Setting LINUX_KERNEL_IMAGE_HEADER=y attempts to include an ARM64 Linux
kernel image header at the start of both U-Boot proper and SPL binaries.
However, some definitions that the image header uses are not included by
the SPL linker script, resulting in a build error. Include them the way
they are included in U-Boot proper's linker script to fix the error.

I won't actually need this header in the SPL, but I need the build to
succeed with SPL and this config both selected. I did test that booting
bare-metal still works on my rk3399 chromebook_kevin with this.
