firmware: arm_scmi: Log the perf domain names in the error paths

Currently, the performance domain names are not logged whenever any
error occurs when processing the OPPs by adding to local data structures
or to the OPP library.

It would be easier to locate the problem if domain name is printed out.
So let us add the performance domain names to the other information
logged already in the error paths.
