This fixes the following link error:
drivers/built-in.o: In function `dw_i2c_probe': of_iommu.c:(.text+0x18c8f0): undefined reference to `__aeabi_uldivmod' make: *** [vmlinux] Error 1

Hi,
Linux next-20130702 link broke for ARM config multi_v7_defconfig. This is with gcc 4.7.2 but I am not sure it matters much here.
This patch repairs the link.
It did not break anything for me on i.MX6 sabre sd, but it does'nt have a designware i2c, so more reviewing/testing is welcome.
Best regards,
V.
