[Intel-gfx] [PATCH v2 00/27] Convert to atomic, part 3.

[Maarten Lankhorst]

This patch requires the following patch from airlied/drm-next:
"[PATCH] drm/atomic: Clear crtc_state->active in drm_atomic_helper_set_config."

Now that suspend/restore is atomic it's time to clean up some
remaining issues. First I clean up the suspend code some more now
that it's atomic.

After that I try to make a better separation between checking and
modeset. This meant that intel_modeset_pipe_config should no longer
touch mode_changed, because it will only be called when a modeset
will already happen to prevent excessive rechecking.

I also clean up the scaler stuff slightly, and move some of it to the
crtc state. Because of feedback on my previous series I'll always add
the plane, instead of handling switching from/to hq mode by waiting
poking scaler 0.

After that it's time to clean up the plane functions, and making sure
the atomic commit runs correctly. This has gone through many
iterations, and I think the way here is the most clean way to deal
with it.

Disabling all planes before a modeset, and committing after, even
if the crtc is in a disabled state provided the most flexibility.
The last callers of the transitional plane helpers are killed, and
intel_set_mode becomes the replacement intel_atomic_commit.

Changes since previous version:
 - Disable all unknown planes correctly by forcing it with a quirk,
  even if sprites were previously enabled it should work without
  requiring a full modeset.
 - Add a plane in the intel_atomic_setup_scalers function again,
   not adding a plane was too tricky.
 - Reorder plane cleanups, 'atomic plane updates in a nutshell'
   is even less scary now.
 - Disable skylake scalers during vblank evasion.
