rdt_find_domain() finds a domain given a resource and a cache-id. This is used by both the architecture code and the filesystem code. After the filesystem code moves to live in /fs/, this helper is either duplicated by all architectures, or needs exposing by the filesystem code. Add the declaration to the global header file. As it's now globally visible, and has only a handful of callers, swap the 'rdt' for 'resctrl'. Move the function to live with its caller in ctrlmondata.c as the filesystem code will not have anything corresponding to core.c.

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.
