Chris Wilson c7bd4c2565 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.
