[igt-dev] [PATCH] tests/amdgpu: add stable pstate tet

[Zhang, Jesse(Jie)]

[AMD Official Use Only - General]

Please Ignore the patch, Since the pipeline build error  because of the lower version libdrm.
" https://gitlab.freedesktop.org/gfx-ci/igt-ci-tags/-/pipelines/991632/failures"
I will send another patch later.
