[PATCH 2/2] i2c: efi: use DIV_ROUND_UP_ULL instead of native division

[Ahmad Fatoum]

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.
