drm/i915: Register ACPI video even when not modesetting

The ACPI video driver defers registration to the i915 driver if the system supports opregion-mediated backlight control. This registration was only being performed in the KMS case. Ensure it's done even if we don't have modesetting enabled. Signed-off-by: Matthew Garrett <[email protected]> Signed-off-by: Eric Anholt <[email protected]>
