[media] zl10353: use div_u64 instead of do_div
Using div_u64() instead of do_div() makes the code slightly more
readable by humans.
[mchehab@osg.samsung.org: originally, this patch was proposed as a bug
fix for a gcc bug. This was solved already, but it is still better to
use div_u64, instead of do_div, so I'm applying it, removing the
comments about the gcc bug]
