Subject: [PATCH v4 18/38] KVM: x86/pmu: Move PMU_CAP_{FW_WRITES,LBR_FMT} into
 msr-index.h header

From: Dapeng Mi <dapeng1.mi@...ux.intel.com>

Move PMU_CAP_{FW_WRITES,LBR_FMT} into msr-index.h and rename them with
PERF_CAP prefix to keep consistent with other perf capabilities macros.

No functional change intended.
