Add amd-pstate test trigger in kselftest, it will load/unload
amd-pstate-ut module to test some cases etc.

Do you still need this?

This can be simpler - see prctl/Makefile or other tests that do arch
checks. Also does this test run on non-amd x86_64 systems?

All x86 or x86_64 AMD systems? Does this run on Intel systems?

What does this do?

Has this script been updated after moving the module to drivers/cpufreq?
Also doesn't this script need to to load the amd_pstate_ut module?

Please take a look at user/test_user_copy.sh for example on modprobe
checks and appropriate test exit codes
