pm: cpupower: Add install and uninstall options to bindings makefile 

Installs the .so and .py files generated by SWIG to system's site packages
directory. This allows the Python bindings to be used system wide. This
commit also includes documentation on setting up and installing the Python
bindings.

developing/using the bindings directly

--------------------------------------



You need to add the Python bindings directory to your $PYTHONPATH.



You would set the path in the Bash terminal or in the Bash profile:



PYTHONPATH=~/linux/tools/power/cpupower/bindings/python:$PYTHONPATH



This allows you to set a specific repo of the bindings to use.





installing/uninstalling

-----------------------



Python uses a system specific site-packages folder to look up modules to import

by default. You do not need to install cpupower to use the SWIG bindings.



You can install and uninstall the bindings to the site-packages with:



sudo make install



sudo make uninstall
