[U-Boot] Bug introduced in x86 cleanup patches

[Graeme Russ]

Hi Wolfgang, Gabe,

My recent x86 cleanup added a small, but very nasty, bug at line 231 of
arch/x86/lib/board.c:

	offset_ptr_ram = offset_ptr_rom + gd->reloc_off

Because offset_ptr_rom is a pointer, when gd->reloc_off gets added, there
is a silent 4x multiplication. The solution is (tested):

	offset_ptr_ram = (Elf32_Rel *)((ulong)offset_ptr_rom
				+ gd->reloc_off);

Or (haven't tested - will test tonight):

	offset_ptr_ram = offset_ptr_rom + (Elf32_Rel *)gd->reloc_off;

I have two options
  - Fix it in the existing commit. As it has not been pulled into
    u-boot/master yet, distribution is likely limited to yourself only
  - Add a fixup patch

Thoughts?

Regards,

Graeme
