Subject: [PATCH] dt-bindings: display: panel: add Ilitek ILI7807S panel
 controller

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, 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.
