ACPI: video: Add backlight=native DMI quirk for Dell G15 5515
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.
