Subject: [PATCH] tools/power/x86/intel-speed-select: Display error on turbo mode disabled
For Intel SST turbo-freq feature to be enabled, the turbo mode on the
platform must be enabled also. If turbo mode is disabled, display error
while enabling turbo-freq feature.

Since this is a trivial patch, I am not sending a PULL request.
