Condat backlight driver: actually allow switching levels We earlier made a change to this driver allowing different backlight levels to be set. However, the old backlight idle logic prevented switching from one backlight level to another without going through a fully-off state. Now that we have the beginnings of new backlight timer logic in BMI+MFW, the old idle logic in the Condat driver layer can be axed, and we fix that driver layer to allow free switching between different backlight levels.
