    ACPI: video: Add backlight=native DMI quirk for Apple iMac11,3
    
    [ Upstream commit 48436f2e9834b46b47b038b605c8142a1c07bc85 ]
    
    Linux defaults to picking the non-working ACPI video backlight interface
    on the Apple iMac11,3 .
    
    Add a DMI quirk to pick the working native radeon_bl0 interface instead.
