[PATCH V3 1/4] selftests: amd-pstate: Modify amd-pstate-ut.sh to basic.sh.

2022-09-14T06:11:45Z

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
