msm: camera: common: Fix for wrong ab ib value send to ICC

While passing ab and ib value to interconnect
for conversion from BPS to ICC units wrong kernel macro is used.
Therefore use correct macro to get the proper ICC units.
In the same way, update the correct flash on active time (use div_u64
instead of do_div).
