When an CPU's performance domain is managed through the SCMI firmware,
let's enable us describe this as a consumer of a power-domain provider,
which is the de-facto standard to use for performance domains. In this
case, let's specify a corresponding power-domain-name, to point out the
corresponding index for it.

Thanks, I just need Viresh's ack for cpufreq changes, we are otherwise all
set with the series. I will pull once I have his ack.
