ACPI / video: Add a disable_native_backlight quirk
ACPI / video: Add a disable_native_backlight quirk

Some laptops have a working acpi_video backlight control, and using native
backlight on these causes a regression where backlight control does not work
when userspace is not handling brightness key events. Disable native_backlight
on these to fix this.
