dt-bindings: display: bridge: Add TI DLPC3433 DSI to DMD

Browse source 
TI DLPC3433 is a MIPI DSI based display controller bridge
for processing high resolution DMD based projectors.

It has a flexible configuration of MIPI DSI and DPI signal
input that produces a DMD output in RGB565, RGB666, RGB888
formats.

It supports upto 720p resolution with 60 and 120 Hz refresh
rates.

Add dt-bingings for it.
