The Dell G15 5515 has the WMI interface (and WMI call returns) expected
by the nvidia-wmi-ec-backlight interface. But the backlight class device
registered by the nvidia-wmi-ec-backlight driver does not actually work.
The amdgpu_bl0 native GPU backlight class device does actually work,
add a backlight=native DMI quirk for this.
