carl9170: Use do_div for 64-bit division to fix 32-bit kernels
Use the do_div macro for 64-bit division. Otherwise, the module will
reference __udivdi3 under 32-bit kernels, which is not allowed in
kernel space.
drivers/built-in.o: In function `carl9170_collect_tally':
cmd.c:191: undefined reference to `__udivdi3'
cmd.c:192: undefined reference to `__udivdi3'
cmd.c:193: undefined reference to `__udivdi3'
