dt-bindings: display: stm32: add a 2nd endpoint
ltdc can have up to 2 endpoints: - dpi external gpios: for rgb panels or external bridge ICs. - dpi internal ios: connected internally to dsi. Note: Refer to the reference manual to know if the dsi is present on your device.

- resets: reset to be used by the device (defined by use of RCC macro).

Required nodes:

- Video port for RGB output.
|

- Video port for DPI RGB output: ltdc has one video port with up to 2

endpoints:
|

- for external dpi rgb panel or bridge, using gpios.
|

- for internal dpi input of the MIPI DSI host controller.
