tools/misc/xenpm: provide core/package cstate residencies
According to Intel 64 and IA32 Architectures SDM 3B Appendix B, Intel
Nehalem/Westmere processors provide h/w MSR to report the core/package
cstate residencies.Extend sysctl_get_pmstat interface to pass the
core/package cstate residencies, and modify xenpm to output those
information.
