drm/gma500: Use backlight_get_brightness() to get the brightness
Use backlight_get_brightness() instead of directly referencing
bd->props.brightness. This will take backlight_is_blank() into account,
properly setting brightness to 0 when screen-blanking has been requested
through the backlight sysfs interface.
