firmware: arm_scmi: Get detailed power scale from perf
In SCMI v3.1 the power scale can be in micro-Watts. The upper layers, e.g.
cpufreq and EM should handle received power values properly (upscale when
needed). Thus, provide an interface which allows to check what is the
scale for power values. The old interface allowed to distinguish between
bogo-Watts and milli-Watts only (which was good for older SCMI spec).
