Title:
  [Hyper-V] Read TSC frequency from a synthetic MSR

Bug description:
  It was found that SMI_TRESHOLD of 50000 is not enough for Hyper-V
  guests in nested environment and falling back to counting jiffies
  is not an option for Gen2 guests as they don't have PIT. As Hyper-V
  provides TSC frequency in a synthetic MSR we can just use this information
  instead of doing a error prone calibration.
