[PATCH 1/2] dt-bindings: display: panel: add Ilitek ILI7807S panel controller

[Arpit Saini]

ILI7807S is a DSI display controller used to drive MIPI-DSI panels.
The DLC DLC0697 1080x1920 LCD panel is based on this controller.

The panel requires a reset GPIO, backlight enable GPIO, I/O voltage
supply (vddi), positive LCD bias supply (avdd) and negative LCD bias
supply (avee). The panel operates in video burst mode with four data
lanes using RGB888 pixel format.
