This converts the IMG SPFI SPI driver to use GPIO descriptors as obtained from the core instead of GPIO numbers. The driver was already relying on the core code to look up the GPIO numbers from the device tree and allocate memory for storing state etc. By moving to use descriptors handled by the core we can delete the setup/cleanup functions and the device state handler that were only dealing with this.

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.
