In preparation for implementing a unit test backend transport for ioctl operations, and making the mailbox available to the cxl/pmem infrastructure, move the existing PCI specific portion of mailbox handling to an "mbox_send" operation. With this split all the PCI-specific transport details are comprehended by a single operation and the rest of the mailbox infrastructure is 'struct cxl_mem' and 'struct cxl_memdev' generic.

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.
