You know the drill: A feature regressed and no one noticed, which
means we are lacking a fully automated testcase. I guess we need to
expose in debugfs somewhere if the edp panel can do psr (if we don't
do that already) to be able to skip the test correctly and then check
with a little igt testcase that we actually achieve psr residency.
Also please poke QA to make sure they actually have a hsw platform
with psr panel.
