Add STM32MP25 support for STM32 SAI. On STM32MP25 the SAI driver does not manage SAI kernel clock rate by chosing its parent clock, dependending on audio stream rate. The driver requests a rate change on SAI kernel clock instead. This rate change is performed with the following guidelines: - Chose highest rate multiple of the audio stream (Try to get clock accuracy within 1000 ppm) - Ensure clock rate compatibility between SAI sub-blocks A&B and between instances sharing the same flexgen. Use clk_rate_exclusive API to fulfill this requirement. The STM32 SAI peripheral does not support the DMA burst mode on STM32MP25. Add a field in compatible structure to manage DMA burst support capability.

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 reStructuredText 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.
