firmware: arm_scmi: Align perf ops to use domain-id as in-parameter
Most scmi_perf_proto_ops are already using an "u32 domain" as an
in-parameter to indicate what performance domain we shall operate upon.
However, some of the ops are using a "struct device *dev", which means that
an additional OF parsing is needed each time the perf ops gets called, to
find the corresponding domain-id.
To avoid the above, but also to make the code more consistent, let's
replace the in-parameter "struct device *dev" with an "u32 domain". Note
that, this requires us to make some corresponding changes to the scmi
cpufreq driver, so let's do that too.
