Convert the STM32 display binding to DT schema format using json-schema.
Split the original bindings in two yaml files:
- one for display controller (ltdc)
- one for DSI controller

In the dsi panel example, clock names in the "clock-names"
field have been swapped:
* "pclk" (peripheral clock) is <&rcc 1 CLK_F469_DSI> on stm32f4
* "ref" (dsi phy pll ref clock) is <&clk_hse> on stm32f4

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.

There is no need anymore to have a "st-display-subsystem" parent node
in the device tree for the ltdc.
