[PATCH] Fix for iBFT compile issues on ARM64

[Konrad Rzeszutek Wilk]

This is a patch to fix the https://lkml.org/lkml/2021/8/3/108 compile
issue which I managed to miss. My apologies for the late fix - please
see the attached patch.

The fix is rather simple - only on X86 do we need to search for the
iBFT under 640KB, so lets ifdef that code.

I also put the patch in linux-next and devel/for-linus-5.15
