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 signal input
produces RGB565, RGB666, RGB888 output format with maximum
of 720p resolution in 60 and 120 Hz refresh rates.

Add dt-bingings for it.

+description: |
+  The DLPC3433 or DLPC3438 controllers provide a convenient,
+  multi-functional interface between system electronics and
+  the DMD, enabling small form factor, low power, and high
