Johan Hovold db96551920 spi: ti-qspi: fix controller deregistration
[ Upstream commit 0c18a1bacb ]

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 3ac066e222 ("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.

Fixes: 3b3a80019f ("spi: ti-qspi: one only one interrupt handler")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
