Len Brown 2af4f9b859 tools/power turbostat: add built-in-counter for IPC -- Instructions per Cycle
Use linux-perf to access the hardware instructions-retired counter.
This is necessary because the counter is not enabled by default,
and also the counter is prone to roll-over -- both of which
perf manages.

It is not necessary to use perf for the cycle counter,
because turbostat already needs to collect delta-aperf
to calcuate frequency.
