drm/i915: Toshiba CB35 has a controllable backlight
commit d4967d8c6d4f52623f2be8eaff0b445dc5863c92 upstream.
The Toshiba CB35 Chromebook (with Celeron 2955U CPU) has a controllable
backlight although its VBT reports otherwise. Apply quirk to ignore the
backlight presence check during backlight setup.
Patch tested by author on Toshiba CB35.
