Since the proposed general fix, fixed the backlight on TUXEDO devices but
broke it on toher ones:
- https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/15679#note_3581777
- https://lore.kernel.org/all/[email protected]/
I'm back here again proposing the fix via quirk.

I therefore rebased
https://lore.kernel.org/all/[email protected]/
to cleanly apply on current drm-tip.

V1-V2: Switch from dmis trings to PCI-IDs
V2-V3: Rebase onto current drm-tip
