msm: mdss: Add absolute backlight control for assertive display
Allow for assertive display to disable backlight updates (except for
updates to turn off display) as an option for automatic backlight mode. If
backlight updates are not prevented, flickering can occur when automatic
backlight mode is enabled and system tries to update backlight value due to
assertive display block controlling backlight values.
