iio: adc: ad7266: Fix potential timestamp alignment issue.
[ Upstream commit 52d349884738c346961e153f195f4c7fe186fcf4 ]
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: 54e018da3141 ("iio:ad7266: Mark transfer buffer as __be16") # aligned_s64 is much newer.
