David Lechner ae5bc07ec9 iio: temperature: maxim_thermocouple: use DMA-safe buffer for spi_read()

Replace using stack-allocated buffers with a DMA-safe buffer for use
with spi_read(). This allows the driver to be safely used with
DMA-enabled SPI controllers.

The buffer array is also converted to a struct with a union to make the
usage of the memory in the buffer more clear and ensure proper alignment.
