[PATCH v3 4/6] iio: adc: ad7380: use IIO_DECLARE_DMA_BUFFER_WITH_TS

[David Lechner]

Use IIO_DECLARE_DMA_BUFFER_WITH_TS() to declare the buffer that gets
used with iio_push_to_buffers_with_ts(). This makes the code a bit
easier to read and understand.

As discussed in v1, this one stays u8 because it is used with both 16
and 32-bit word sizes.

v3 changes:
* Use IIO_DECLARE_DMA_BUFFER_WITH_TS() and drop __align()

v2 changes:
* None (but I messed up and there was supposed to be a change).
