[Intel-gfx] [PATCH v2 06/14] drm/i915: Reorganize plane register writes to make them more atomic

From: Ville Syrjälä Some observations about the plane registers: - the control register will self-arm if the plane is not already enabled, thus we want to write it as close to (or ideally after) the surface register - tileoff/linoff/offset/aux_offset are self-arming as well so we want them
