iio: accel: adxl355: Make timestamp 64-bit aligned using aligned_s64

[ Upstream commit 1bb942287e05dc4c304a003ea85e6dd9a5e7db39 ]

The IIO ABI requires 64-bit aligned timestamps. In this case insufficient
padding would have been added on architectures where an s64 is only 32-bit
aligned.  Use aligned_s64 to enforce the correct alignment.
