Subject: [PATCH 18/27] tools/power/x86/intel-speed-select: Improve error display for turbo-freq feature
This change adds improved error display and handling for commands related
to turbo-freq feature. The changes include:
- Replace perror/fprintf with helpful error message
- Error for not specifying TDP level when required
- Show error for invalid bucket number
- Show message to enable core-power before enabling turbo-freq feature
