drm/i915: Wait for scanout to stop when sanitizing planes
When we sanitize planes let's wait for the scanout to stop before we let the subsequent code tear down the ggtt mappings and whatnot. Cures an underrun on my ivb when I boot with VT-d enabled and the BIOS fb gets thrown out due to stolen being considered unusable with VT-d active.
