[PATCH v2 1/1] spi: spi-fsl-qspi: use devm_spi_register_controller

[Volker Haspel]

The driver does not clearly unregister the spi controller.
Therefore calling an unbind and bind again will end up in a
Kernel crash.

The function devm_spi_register_controller will automatically
be unregister the SPI device.
