x86 boot: x86_64 efi compiler warning fix
Fix a compiler warning. Rather than always casting a u32 to a pointer (which generates a warning on x86_64 systems) instead separate the x86_32 and x86_64 assignments entirely with ifdefs. Until other recent changes to this code, it used to have x86_64 separated like this.
