drivers: spi: sam0: Implement DMA async API This adds support for the async API for SAM0 SERCOM SPI using DMA to drive the device. This implementation does the reload for both transmit and receive in the receive DMA handler. Doing this simplifies the implementation but means that the transmit drains completely, resulting in the SPI clock pausing between buffers while both are reloaded in the receive handler. Tested with tests/drivers/spi/spi_loopback and several simple programs monitored with a logic analyzer. Signed-off-by: Derek Hageman <hageman@inthat.cloud>
