Just like BDW, those registers are on the respective pipe powell, and if we
don't restore them bad things happen! like not flipping anymore because the
primary plane flip done interrupt is disabled.
With that, the torture test that is kms_flip seems to be fairly happy, it's
been running (and passing tests) for a good 20 minutes and is still going.
