dt-bindings: arm: stm32: add required #clock-cells property
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.
