display: Support dim brightness setting

The dim brightness setting feature had been supported before
but it was no longer available after ce471ec18f19bb184848f4c84e813b834ef4bdee commit.
Although there were descriptions and functions provided for setting dim brightness,
it's not right that it cannot be used, so it is restored.
