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.

This patch causes a regression and shouldn't be applied without the fix
in https://lkml.org/lkml/2020/9/28/300.
Looks like the fix didn't make it yet, so I'll drop the patch.
