Touching the VGA resources on an IVB EFI machine causes hard hangs when we then kick out the efifb. Ouch. Apparently this also prevents unclaimed register errors on hsw and hard machine hangs on my i855gm when trying to unbind fbcon. Also, we want this to make I915_FBDEV=n safe. v2: Rebase and pimp commit message. v3: We also need to unregister the vga console, otherwise the unbind of the fb console before module unload might resurrect it again. v4: Ignore errors when the vga console is already unregistered - this can happen when e.g. reloading i915.ko.
