On Xilinx-AMD Versal and Versal-NET, there exist both inter-processor-interrupts with corresponding message buffers and without such buffers. Add a routine that, if the corresponding DT compatible string "xlnx,versal-ipi-mailbox" is used then a Versal-based SOC can use a mailbox Device Tree entry where both host and remote can use either of the buffered or bufferless interrupts.

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.
