The selected mode changes how color component bits are assigned to the LCD_DATA pins. This must match the board wiring. On Colibri iMX6ULL, for example, only 18 LCD data lines are routed. A 24-bit panel can still be connected by wiring the available LCD_DATA signals to the appropriate panel inputs. Without describing the resulting interface format, LCDIF may assign the color components to different data lines, causing shifted colors. Add interface-pix-fmt so the binding can describe the configured LCDIF bus format. The same property is already used by display/imx/fsl,imx-parallel-display.yaml.
