[PATCH][v7] KVM: X86: support APERF/MPERF registers

Guest kernel reports a fixed cpu frequency in /proc/cpuinfo, this is confused to user when turbo is enable, and aperf/mperf can be used to show current cpu frequency after 7d5905dc14a "(x86 / CPU: Always show current CPU frequency in /proc/cpuinfo)" so guest should support aperf/mperf capability T
