Andrew Murray 21137301de arm64: KVM: Fix perf cycle counter support for VHE
The kvm_vcpu_pmu_{read,write}_evtype_direct functions do not handle
the cycle counter use-case, this leads to inaccurate counts and a
WARN message when using perf with the cycle counter (-e cycle).

Let's fix this by adding a use case for pmccfiltr_el0.
