iio: adc: hx711: Fix buffer alignment in iio_push_to_buffers_with_timestamp()
To make code more readable, use a structure to express the channel
layout and ensure the timestamp is 8 byte aligned.
Found during an audit of all calls of this function.
Fixes: d3bf60450d47 ("iio: hx711: add triggered buffer support")
