Subject: [PATCH 2/8] iio: adc: mt6360-adc: use aligned_s64 for timestamp

Follow the pattern of other drivers and use aligned_s64 for the
timestamp. This will ensure that the timestamp is correctly aligned on
all architectures. It also ensures that the struct itself it also 8-byte
aligned so we can drop the explicit __aligned(8) attribute.
