perf/x86: Add an MSR PMU driver
This patch adds an MSR PMU to support free running MSR counters. Such
as time and freq related counters includes TSC, IA32_APERF, IA32_MPERF
and IA32_PPERF, but also SMI_COUNT.
The events are exposed in sysfs for use by perf stat and other tools.
The files are under /sys/devices/msr/events/
