Revert "[MTD] m25p80.c code cleanup"
This reverts commit 75d0ee2202b5740e94e913d8a52f91c6557c4c81. Although it seems ObviouslyCorrectâ„¢, the spi_write() call uses DMA, while spi_write_then_read() does not. Since our buffer is on the stack, we must use the latter even though we don't actually want to read anything back.
