drm/i915: register backlight device also when backlight class is a module
Ville and I were wondering why his laptop was missing the
intel_backlight sysfs interface. Turns out we never register it when
CONFIG_BACKLIGHT_CLASS_DEVICE=m. This has been broken ever since the
i915 native backlight interface was added.
