Jonathan Cameron 67460e8c9a iio:common:ssp_sensors fix warnings due to 32 bit instead of 64 bit passed to do_div
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:
   In file included from drivers/iio/common/ssp_sensors/ssp_iio.c:20:0:
   drivers/iio/common/ssp_sensors/ssp_iio_sensor.h: In function 'ssp_convert_to_freq':

   include/asm-generic/div64.h:35:17: note: expected 'uint64_t *' but argument is of type 'int *'
   drivers/iio/common/ssp_sensors/ssp_iio.c: In function 'ssp_common_process_data':
   include/linux/iio/buffer.h:142:32: warning: 'calculated_time' may be used uninitialized in this function [-Wuninitialized]
   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.
