Ashwin Chaugule b5ca687960 Perf: Save and restore counters through powercollapse ...

Update the active perf counter data structs with the most recent
values of the counters before going into powercollapse and restore
the corresponding hardware counters with these values when coming
out of it.

This change fixes a bug where the counter outputs show wild swings
when CPU power collapse is enabled.
