spi: fsl-dspi: fix use-after-free in remove path
spi_unregister_controller() not only unregisters the controller, but
also frees the controller. This will free the driver data with it, so
we must not access it later dspi_remove().
Solve this by allocating the driver data separately from the SPI
controller.
