ARM: SAMSUNG: Add a callback 'notify_after' for PWM backlight control

The callback 'notify_after' was added to struct platform_pwm_backlight_data
provided by PWM backlight driver. Therefore, this patch adds a callback
'notify_after' which can be called after pwm_enable, pwm_disable and
pwm_config.
