iio: adc: dln2: Use aligned_s64 for timestamp

[ Upstream commit 5097eaae98e53f9ab9d35801c70da819b92ca907 ]

Here the lack of marking allows the overall structure to not be
sufficiently aligned resulting in misplacement of the timestamp
in iio_push_to_buffers_with_timestamp(). Use aligned_s64 to
force the alignment on all architectures.
