drm/i915: Acer C720 and C720P have controllable backlights
commit 2e93a1aa9ca455aa3ad0294bcd6d66f38bf8b758 upstream.
The Acer C720 and C720P Chromebooks (with Celeron 2955U CPU) have a
controllable backlight although their VBT reports otherwise. Apply quirk
to ignore the backlight presence check during backlight setup.
