  Modify amd-pstate-ut.sh to basic.sh.
The purpose of this modification is to facilitate the subsequent
addition of gitsource, tbench and other tests.
Then you can specify test case in kselftest/amd-pstate, for example:
sudo ./run.sh -c basic, this command only test basic kernel funcitions.
The detail please run the below script.
./run.sh --help

Is there a reason to delete followed by a create?  It is cleaner to rename amd-pstate-ut.sh
it to basic.sh first and then make changes.
