Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.
Instead of manually checking the power state in struct
backlight_properties, use backlight_is_blank().
