Chris Wilson edd586fe70 drm/i915: Discard BIOS framebuffers too small to accommodate chosen mode ...

If the inherited BIOS framebuffer is smaller than the mode selected for
fbdev, then if we continue to use it then we cause display corruption as
we do not setup the panel fitter to upscale.

    drm/i915: Wrap the preallocated BIOS framebuffer and preserve for KMS fbcon v12

v2: Add a debug message to track the discard of the BIOS fb.
v3: Ville pointed out the difference between ref/unref
