x86 boot: x86_64 efi compiler warning fix

Browse source 
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.
