urgent power management fixes for final 4.18.

These fix the scope of a recent intel_pstate driver optimization
used incorrectly on some systems due to processor identification
ambiguity and fix a few issues in the turbostat utility, including
three recent regressions.

Specifics:

 - Use ACPI FADT preferred PM Profile to distinguish Skylake
   desktop processors from some server ones with the same model
   number in order to limit the scope of the recent IO-wait boost
   optimization to servers, as intended (Srinivas Pandruvada).

 - Fix several issues in the turbostat utility:
   * Fix the -S option on 1-CPU systems (Len Brown).
   * Fix computations using incorrect processor core counts (Artem
     Bityutskiy).
   * Fix the x2apic debug message (Len Brown).
   * Fix logical node enumeration to allow for non-sequential
     physical nodes (Prarit Bhargava).
   * Fix reported family on modern AMD processors (Calvin Walton).
   * Clarify the RAPL column information in the man page (Len Brown).

Sorry for the broken message, I'll send the correct one shortly.
