Chris Wilson d2dff872ac drm/i915: Attach a fb to the load-detect pipe 
We need to ensure that we feed valid memory into the display plane
attached to the pipe when switching the pipe on. Otherwise, the display
engine may read through an invalid PTE and so throw an PGTBL_ER
exception.

As we need to perform load detection before even the first object is
allocated for the fbdev, there is no pre-existing object large enough
for us to borrow to use as the framebuffer. So we need to create one
and cleanup afterwards. At other times, the current fbcon may be large
enough for us to borrow it for duration of load detection.

Found by assert_fb_bound_for_plane().
