KVM: x86/pmu: Replace pmc_perf_hw_id() with perf_get_hw_event_config()
With the help of perf_get_hw_event_config(), KVM could query the correct EVENTSEL_{EVENT, UMASK} pair of a kernel-generic hw event directly from the different *_perfmon_event_map[] by the kernel's pre-defined perf_hw_id. Also extend the bit range of the comparison field to AMD64_RAW_EVENT_MASK_NB to prevent AMD from defining EventSelect[11:8] into perfmon_event_map[] one day.
