If the number of screen refreshes is too small or user suspends the device before it finishes the scheduled screen refreshes, last_str will be different from the target strength for the current inputs. And when device goes into idle power collapse mode and exits, AD will switch to manual strength mode with last_str for two frames. After that, AD will go back to auto strength mode with the target strength. Since last_str and target strength may be different, flickers will be seen every time AD mode switch happens. This change fixes this above issue by reading the AD strength register and updating the value to last_str when AD mode switches from manual mode to auto strength mode.
