Minggui Cao b3bd153180 hv: expose PEBS capability and MSR as PMU_PT flag 
Requirement: in CPU partition VM (RTVM), vtune or perf can be used to
sample hotspot code path to tune the RT performance, It need support
PMU/PEBS (Processor Event Based Sampling). Intel TCC asks for it, too.

It exposes PEBS related capabilities/features and MSRs to CPU
partition VM, like RTVM. PEBS is a part of PMU. Also PEBS needs
DS (Debug Store) feature to support. So DS is exposed too.

Limitation: current it just support PEBS feature in VM level, when CPU
traps to HV, the performance counter will stop. Perf global control
MSR is used to do this work. So, the counters shall be close to native.
