    display: Use the native intel backlight controller
    
    If the i915 driver exposes a native ACPI interface to modify the panel
    backlight use it in preference to the generic interfaces. On multi-GPU
    systems, the panel backlight is meant to be connected via the IGP and
    this ensures that we always find the right interface.
    
    Fixes:
    
          Bug 29273 - XORG Intel driver chooses wrong acpi_video to control
                      brightness in multi-GPU system
