Replaces the open-coded checks of the state, with the
backlight_get_brightness() helper. This increases readability
of the code and align the functionality across the drivers.

Futhermore drop the debug prints in update_status().
If we need debug printing then we can add it to the backlight core.

v2:
  - Use backlight_get_brightness()
