msm: mdss: Notify AD only when brightness changes
Previously, any backlight change to panel will trigger assertive
display (AD) feature to conduct screen refresh calls. This will
trigger unnecessary screen refresh if AD is enabled together with
CABL feature. This change modifies the backlight notification
mechanism to notify AD only when the Android brightness level
is changed.
