drm/i915: Ignore VBT backlight presence check on HP Chromebook 14
commit c675949ec58ca50d5a3ae3c757892f1560f6e896
drm/i915: do not setup backlight if not available according to VBT
caused a regression on the HP Chromebook 14 (with Celeron 2955U CPU),
which has a misconfigured VBT. Apply quirk to ignore the VBT backlight
presence check during backlight setup.
