[ Upstream commit e9090e70e618cd62ab7bf2914511e5eea31a2535 ] Similar to other protocol ops, it's useful for an scmi module driver to get the number of supported performance domains, hence let's make this available by adding a new perf protocol callback. Note that, a user is being added from subsequent changes.

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.
