STM32MP25 SoC features a new version of the LTDC IP. Add its compatible
to the list of device to probe and implement its quirks.
This hardware supports a pad frequency of 150MHz and a peripheral bus
clock.

The LCD-TFT Display Controller (LTDC) handles display composition,
scaling and rotation. It provides a parallel digital RGB flow to be
used by display interfaces.

On STM32MP25 SoC, the syscfg peripheral provides a clock to the display
subsystem through a multiplexer. Since it only provides a single clock,
the cell value is 0.
Doing so allows the clock consumers to reach the peripheral and gate the
clock accordingly.

- 'pixel_clk' is dependent from 'clk_pix_lvds' because of the LTDC clock
domains. They also need to be sync to get a coherent pixel rate though
the display clock tree (which explains the LVDS phandle on the LTDC node
in the device-tree).
