Instead encode the FREEZE state via the CPU state we allow the interesting subsystems (MCE, microcode) to query the power subsystem directly. Most notifiers are not interested at all in this information so rather have explicit calls to freeze_active() instead adding complexity to the rest of the users of the CPU notifiers.
