iio: adc: ad7266: Fix potential timestamp alignment issue.

Browse source

[ Upstream commit 52d3498847 ]

On architectures where an s64 is only 32-bit aligned insufficient padding
would be left between the earlier elements and the timestamp. Use
aligned_s64 to enforce the correct placement and ensure the storage is
large enough.

Fixes: 54e018da31 ("iio:ad7266: Mark transfer buffer as __be16") # aligned_s64 is much newer.
