[PATCH 2/5] dt-bindings: arm: stm32: Add clock-controller sub-node to STM32MP2 SYSCFG

[Gabriel Fernandez]

The LTDC pixel clock multiplexer of the STM32MP23x and STM32MP25x
SYSCFG is described by a clock-controller sub-node of the SYSCFG node.

Add this sub-node to the SYSCFG binding. It is required on STM32MP23x
and STM32MP25x and not allowed on the other SoCs.
