To analyze the exit events with perf, we need kvm_perf.h to be added in
the arch/powerpc directory, where the kvm tracepoints needed to trace
the KVM exit events are defined.

This patch adds "kvm_perf_book3s.h" to indicate that the tracepoints are
book3s specific. Generic "kvm_perf.h" then can just include
"kvm_perf_book3s.h".

- Not exporting the exit reasons compared to previous patchset (suggested 
by Paul)
