counter: stm32-timer-cnt: add support for stm32mp25
Add support for STM32MP25 SoC. There are new counter modes that may be implemented in later. Still, use newly introduced compatible to handle this new HW variant and avoid being blocked with existing compatible in SoC dtsi file. Modes supported currently still remains compatible. New timer 20 has encoder capability, add it to the list.
