[PATCH 05/13] xenpm: Change get-cpufreq-para output for internal



When using HWP, some of the returned data is not applicable.  In that
case, we should just omit it to avoid confusing the user.  So switch to
printing the base and turbo frequencies since those are relevant to HWP.
Similarly, stop printing the CPU frequencies since those do not apply.
