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.
