firmware: arm_scmi: Fixup perf power-cost/microwatt support
[ Upstream commit c3638b851bc1ca0022dca9d6ca4beaa6ef03a216 ]
The perf power scale value would currently be reported as bogowatts if the
platform firmware supports microwatt power scale and meets the perf major
version requirements. Fix this by populating version information in the
driver private data before the call to protocol attributes is made.
