firmware: arm_scmi: Add power_scale_mw_get() interface

Browse source

Add a new interface to the existing perf_ops and export the information
about the power values scale.

This would be used by the cpufreq driver and Energy Model framework to
set the performance domains scale: milli-Watts or abstract scale.
