[Intel-gfx] [PATCH 0/6] drm/i915: Unfify some modeset sequences

[ville.syrjala at linux.intel.com]

We have some random variation in the ordering of the plane related stuff
during modeset. This series tries to unify that a little bit.

We could take this a bit further even and enable the planes as the very
last step of modeset. But for now I more of less kept the general sequence
unchanged.

The other bigger change here is that now we actually disable/enable sprites
around modeset.
