powerpc: Partial revert of "Context switch more PMU related SPRs"
In commit 59affcd I added context switching of more PMU SPRs, because
they are potentially exposed to userspace on Power8. However despite me
being a smart arse in the commit message it's actually not correct. In
particular it interacts badly with a global perf record.
We will have to do something more complicated, but that will have to
wait for 3.11.
