Takashi Sakamoto 40d4c76120 firewire: core: fix undefined reference error in ARM EABI ...

For ARM EABI, GCC generates a reference to __aeabi_uldivmod when compiling
a division of 64-bit integer with 32-bit integer. This function is not
available in Linux kernel. In such cases, helper macros are defined in
include/linux/math64.h.

This commit replaces the division with div_u64().
