disp: msm: sde: add support for digital dimming

Browse Source 
Add a new connector property to allow DC dimming feature to set
dimming backlight LUT. This change also adds a connector event
for client to register for backlight info needed for digital dimming
feature, including OS brightness, OS brightness_max, panel_backlight,
panel_backlight_max, and scale factors from ABA and LTM features.
