Imre Deak 9d6612516d drm/i915: unbind fbs from crtcs during driver unload 
So far during driver unload we called drm_framebuffer_cleanup() for the
fbdev fb, which only removes the fb from the drm fb list regardless of
its reference count, but leaves the fb bound on an active crtc. Since
the fb's backing storage was freed this could mean we scan some random
memory content out afterwards. It's not a big issue since the fb is
allocated from stolen memory and afaik there is no other user for that
than i915. It's still cleaner to properly unbind the fb and disable the
crtc, which is what drm_framebuffer_remove() does.

Note that after

we call drm_framebuffer_cleanup() only after dropping the last reference
on the fb, but that won't happen since we don't unbind the fb. This
results in a drm core warn about a leaked fb.
