Add a new stm32mp25 compatible to stm32-lptimer dt-bindings, to support STM32MP25 SoC. Some features has been added to the low-power timer like new capture compare channels (hence more PWM channels, and PWM input capture). Some registers/bits has been revisited to support this. So introduce a new compatible to handle this diversity.
