Shenlin Liang da7b1b525e perf kvm/riscv: Port perf kvm stat to RISC-V 
'perf kvm stat report/record' generates a statistical analysis of KVM
events and can be used to analyze guest exit reasons.

To record kvm events on the host:
 # perf kvm stat record -a

To report kvm VM EXIT events:
 # perf kvm stat report --event=vmexit
