Benjamin Valentin 8a99bd0da8 drivers: spi: spi_sam0: fix spi_sam0_fast_txrx() ... The optimisation in `spi_sam0_fast_txrx()` is broken, loading two bytes into the `DATA` register in rapid succession will lose one byte. This can be observed by running `tests/drivers/spi/spi_loopback`. The test will get stuck in `spi_sam0_fast_txrx()` forever waiting for the final byte. Undo this small optimisation and only load the next byte into the `DATA` register after the response has been received. This fixes `tests/drivers/spi/spi_loopback`.
