 * reloaded after a power collapse which is not how the PWR counters behaved on
 * legacy hardware. In order to limit the disruption on the rest of the system
 * we go out of our way to ensure backwards compatibility. Since RBBM counters
 * are in short supply, we don't emulate PWR:0 which nobody uses - mark it as
