Also change to div64_u64 in one place to avoid loss of precision
(was dividing a 32 bit number by a 64 bit number, but casting this
to 64 bit divided by 32 bit) Those divide functions certainly have
esoteric naming!
Fixes warnings with asm-generic/div64.h do_div such as:

drivers/iio/common/ssp_sensors/ssp_iio.c:83:10: note: 'calculated_time' was declared here
Fixed by using straight coded version as per the description in the
div64.h header, thus ensuring no issue with 32 bit integers.
