Certain SCMI performance domains may have restrictions on the set level and/or limits operation. If the SCMI domain supports fastchannel and the set operations are not allowed, then any attempts to fetch the fastchannel information for set level and/or limits operation will result in the SCMI platform returning SCMI_ERR_SUPPORT. However, since this information about the domain is already known to the agent(OSPM here) obtained via PERF_DOMAIN_ATTRIBUTES, the agent(OSPM) can avoid calls to the firmware trying to fetch the fastchannel information for the same. Add those checks and skip querying the fastchannel information from the firmware based on the information collected during the domain enumeration stage.

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.
