    Like DRM when kscreen is not used, scale value is loaded from a config
    file.
    
    Config format is
    [HWComposerOutputs][0]
    Scale=N
    
    The 0 is to map similarly to DRM and support multi-screen, but with a screen index
    rather than a UUID based on EDID.
    
    Because we don't support multi screen this is always 0 for now.
