    drm/i915: Take a runtime pm wakeref for atomic commits

    Before we start prepping the system for an atomic modeset, wake the
    device up. We then keep track of this wakeref until we complete the
    atomic commit, so we hold keep the device awake for all potential HW
    access, and do not allow the device to sleep with a pending modeset.

Note to self: intel_rps_mark_interactive() is not let off the hook, as it's
check to see whether RPS is alive is racy.
