Ulf Hansson c3af26f536 firmware: arm_scmi: Extend perf protocol ops to get information of a domain ...

[ Upstream commit 3d99ed6072 ]

Similar to other protocol ops, it's useful for an scmi module driver to get
some generic information of a performance domain. Therefore, let's add a
new callback to provide this information. The information is currently
limited to the name of the performance domain and whether the set-level
operation is supported, although this can easily be extended if we find the
need for it.
