This adds a new spi_engine_precompile_message() function to the ADI AXI SPI Engine driver to populate the xfer->effective_speed_hz field since the SPI core doesn't/can't do this for us. This driver is already using spi_delay_to_ns() which depends on effective_speed_hz to get an accurate value in some cases. Having an effective_speed_hz value can also be used in future changes to simplify other code.

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.
