spi: ti-qspi: fix controller deregistration

Make sure to deregister the controller before disabling underlying
resources like clocks during driver unbind.

Note that the controller is suspended before disabling and releasing
resources since commit 3ac066e2227c ("spi: spi-ti-qspi: Suspend the
queue before removing the device") which avoids issues like unclocked
accesses but prevents SPI device drivers from doing I/O during
deregistration.
