vpmu intel: Dump vpmu infos in 'q' keyhandler
This patch extends the printout of the VPCU infos of the keyhandler 'q'.
If vPMU is enabled is on the VCPU and active lines are printed like
(when running HVM openSuSE-12.3 with 'perf top');
(XEN) vPMU running
(XEN) general_0: 0x000000ffffff3ae1 ctrl: 0x000000000053003c
(XEN) fixed_1: 0x000000ff90799188 ctrl: 0xb
This means general counter 0 and fixed counter 1 are running with showing
their contents and the contents of their configuration msr.
