spi: spi-fsl-dspi: Fix lockup if device is removed during SPI transfer
During device removal, 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
removal reverse-matches the probe function, where SPI controller is
registered at the end.
Fixes: 05209f457069 ("spi: fsl-dspi: add missing clk_disable_unprepare() in dspi_remove()")
