Here we plan to support virtual PMU for guest by full software emulation, so define some basic structs and functions preparing for futher steps. Define struct kvm_pmc for performance monitor counter and struct kvm_pmu for performance monitor unit for each vcpu. According to ARMv8 spec, the PMU contains at most 32(ARMV8_PMU_MAX_COUNTERS) counters. Since this only supports ARM64 (or PMUv3), add a separate config symbol for it.
