iio: adc: ad9467: use DMA safe buffer for spi

Make sure we use a DMA safe buffer (IIO_DMA_MINALIGN) for all the spi
transfers. Only relevant for writes since for reads
spi_write_then_read() is used which does not require DMA safe buffers.

Also note that for consistency, ad9467_spi_read() is also taking struct
ad9467_state as a parameter (even if not really needed).
