tools/power turbostat: simplify output, add Avg_MHz 

Use 8 columns for each number ouput.
We don't fit into 80 columns on most machines,
so keep the format simple.

Print frequency in MHz instead of GHz.
We've got 8 columns now, so use them to
show low frequency in a more natural unit.

Many users didn't understand what %c0 meant,
so re-name it to be %Busy.

Add Avg_MHz column, which is the frequency that many
users expect to see -- the total number of cycles executed
over the measurement interval.

People found the previous GHz to be confusing, since
it was the speed only over the non-idle interval.
That measurement has been re-named Bzy_MHz.

Above the cycle soaker drives cpu5 up its 3.8 GHz turbo limit

Note that cpu1 and cpu7 are HT siblings within core8.
As cpu7 is very busy, it prevents its sibling, cpu1,
Note that cpu1 and cpu5 are HT siblings within core1.
As cpu5 is very busy, it prevents its sibling, cpu1,
from entering a c-state deeper than c1.
Note that turbostat reports average GHz of 3.63, while
the arithmetic average of the GHz column above is lower.
This is a weighted average, where the weight is %c0. ie. it is the total number of
un-halted cycles elapsed per time divided by the number of CPUs.
.SH SMI COUNTING EXAMPLE
On Intel Nehalem and newer processors, MSR 0x34 is a System Management Mode Interrupt (SMI) counter.
This counter is shown by default under the "SMI" column.

Note that the Avg_MHz column reflects the total number of cycles executed
divided by the measurement interval. If the %Busy column is 100%,
then the processor was running at that speed the entire interval.
The Avg_MHz multiplied by the %Busy results in the Bzy_MHz --
which is the average frequency while the processor was executing --
not including any non-busy idle time.
