ACPI: CPPC: Evaluate performance-control PCC use once
cppc_set_perf() evaluates the same immutable address-space predicates
before and after each phase of a performance-control update. This repeats
the three-control PCC test three times for every target request.
Evaluate the predicate once after resolving the control descriptors and
reuse the result throughout the transaction.
