Abhishek Goel 901d32bc69 cpupower : Auto-completion for cpupower tool
This script adds support for auto-completion for cpupower tool.
Added support for auto-completion of all the eight commands for
cpupower tool and their all subsequent sub-commands, wherever
possible.

A sample output after applying this script -
