-    cpufreq/intel_pstate: Add function to check that all MSR's are valid
-    
-    Some VMs seem to try to implement some MSRs but not all the registers
-    the driver needs.  Check to make sure all the MSR that we need are
-    available. If any of the required MSRs are not available refuse to
-    load.
