[PATCH] power: supply: da9150: use div64_u64() instead of do_div()

[Qing Wang]

From: Wang Qing <wangqing@xxxxxxxx>

do_div() does a 64-by-32 division.
When the divisor is u64, do_div() truncates it to 32 bits, this means it
can test non-zero and be truncated to zero for division.

fix do_div.cocci warning:
do_div() does a 64-by-32 division, please consider using div64_u64 instead.
