On architectures where an s64 is not 64-bit aligned, this may result
insufficient alignment of the timestamp and the structure being too small.
Use aligned_s64 to force the alignment.

Fixes: a1caeebab07e ("iio: adc: ad7768-1: Fix too small buffer passed to iio_push_to_buffers_with_timestamp()") # aligned_s64 newer
