backlight: Use backlight_get_brightness() throughout
Introduce the backlight_get_brightness() helper in all video/backlight/* drivers. This simplifies the code and align the implementation of the update_status() operation across the different backlight drivers. Some of the drivers gains a little extra functionality by the change as they now respect the fb_blank() ioctl.
