Subject[PATCH 03/27] tools/power/x86/intel-speed-select: Enhance core-power info command
Date
In addition to CLOS enable status, also show the core-power feature
status. This will help why clos enable status didn't give desired
results as the core-power feature may be disabled or unsupported.

The new display looks as follows:

$intel-speed-select core-power info
Intel(R) Speed Select Technology
..
package-0
die-0
cpu-0
core-power
support-status:supported
enable-status:enabled
clos-enable-status:1
priority-type:0

In the above display "support-status" and "enable-status", shows the
status of the core-power feature and "clos-enable-status", shows the
status of the clos.
