spi: spi-fsl-dspi: Fix lockup if device is shutdown during SPI transfer
During shutdown, the driver should unregister the SPI controller
and stop the hardware. Otherwise the dspi_transfer_one_message() could
wait on completion infinitely.
Additionally, calling spi_unregister_controller() first in device
shutdown reverse-matches the probe function, where SPI controller is
registered at the end.
Fixes: dc234825997e ("spi: spi-fsl-dspi: Adding shutdown hook")
