ACPI / processor: Finish making acpi_processor_ppc_has_changed() void
Commit bca5f557dcea "ACPI / processor: Make acpi_processor_ppc_has_changed()
void" changed one of the declarations of acpi_processor_ppc_has_changed()
to return void, but the !CPU_FREQ version still returns int. Let's return
void to be consistent.
