[Intel-gfx] [PATCH 4/7] drm/i915: Use a custom restore_fbdev_mode hook

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Disable sprite planes and cursors when restoring the fbdev mode.
This is actually only needed in case the modeset gets optimized into a
set_base, but that's a fairly important case these days.
Should makes oopses more readable if they're not covered by spriteas and
cursors.
