drm/i915: Remove too early plane enable on pre-PCH hardware Enabling the plane before we have assigned valid address means that it will access random PTE (often with conflicting memory types) and cause GPU lockups. However, enabling the plane too early appears to workaround a number of bugs in our modesetting code.
