drm/nouveau: Don't register backlight when another backlight should be used (v2)
Before this commit when we want userspace to use the acpi_video backlight
device we register both the GPU's native backlight device and acpi_video's
firmware acpi_video# backlight device. This relies on userspace preferring
firmware type backlight devices over native ones.
Registering 2 backlight devices for a single display really is
undesirable, don't register the GPU's native backlight device when
another backlight device should be used.
Changes in v2:
- Add nouveau_acpi_video_backlight_use_native() wrapper to avoid unresolved
symbol errors on non X86
