Is there anything blocking this patch from being applied?  It
brings back the tools needed to run the amd-pstate tests into the
kselftest installation directory.

I could try to run the test on an AMD platform and check it's
working as before, but there was no change in the tools
themselves and I've checked the scripts get installed correctly
now like before.  We might also actually run this test in
KernelCI since there are a few AMD platforms available.

Thanks,
Guillaume
