iio: light: opt4060: Fix pointer type passed to div_u64_rem()

div_u64_rem() expects a u32 * for the remainder, but
opt4060_read_ev_period() passes val2, which is declared as an
int *. While this has no functional impact, it triggers a pointer type
mismatch.

There is no behavioural change because int and u32 have the same
size and representation on all supported architectures, and the
remainder is always less than MICRO, so it fits within the positive
range of int.

Use a local u32 to receive the remainder before assigning it to
*val2.
