Prepare support for STM32F4 spi variant by introducing compatible configuration data. Move STM32H7 specific stuff to compatible data structure: - registers & bit fields - routines to control driver - baud rate divisor definitions - fifo availability - split IRQ functions to parts to be called when the IRQ occurs and for threaded interrupt what helps to provide less discontinuous mode for drivers without FIFO.

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.
