[PULL] drm-intel-fixes

Hi Dave -

Here's the display power stuff that Daniel and I were a bit hesitant to
queue to v4.5 at this late stage, but since you said, "looks fairly self
contained, if it make skylake suck less I'm all for it", here goes.

Most of the commits are quite similar, ensuring the display power
doesn't vanish under us during hardware access. Also do note that it's
not just Skylake that's affected.

We've tested this against -rc4, and rebased on top of -rc5 today. We'll
keep testing, but I'm sending the pull request early as I'm not around
later this week, and it'll also give you more time to decide whether to
pull or not.

I've asked Imre to let you know by end of Thursday our time if any new
bugs show up in testing.

BR,
Jani.
