tools/power/x86/intel-speed-select: Display punit info

Display punit info for platforms with new api_version.
For platforms with old api_version, don't display the punit info to be
backward compatible.

For example:

Intel(R) Speed Select Technology
Executing on CPU model:173[0xad]
 package-0
  die-0
    powerdomain-0
      cpu-0
        get-config-current_level:0
 package-0
  die-0
    powerdomain-3
      cpu--1
        get-config-current_level:0
 package-0
  die-0
    powerdomain-4
      cpu--1
        get-config-current_level:0
