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.
