drm/i915: Ignore VBT backlight presence check on HP Chromebook 14
commit 724cb06fa9b1e1ffd98188275543fdb3b8eaca4f upstream.

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.
