Michael Ellerman 8f6c5b6c12 powerpc/perf: Freeze PMC5/6 if we're not using them ...

commit 7a7a41f9d5 upstream.

On Power8 we can freeze PMC5 and 6 if we're not using them. Normally they
run all the time.

As noticed by Anshuman, we should unfreeze them when we disable the PMU
as there are legacy tools which expect them to run all the time.
