DD2.1 does not have to flush the ERAT after a state-loss idle. It also
does not have to save and restore MMCR0 (although it does have to save
restore in deep idle states, like other PMU registers).  

Minor nit, can we do this as two separate commits in case we discover one is
broken.

Good idea, resent.

Thanks,
