64-bit division on 32-bit platforms is normally handled by libgcc, which, like the kernel, we don't link against in barebox. Instead we have a number of division helpers that should be used for 64-bit division, which either expand to a normal division if possible or to an out-of-line division. Make use of this to fix compilation for 32-bit.
