dt-bindings: rtc: stm32: introduce new st,stm32mp25-rtc compatible
Introduce new st,stm32mp25-rtc compatible. It is based on st,stm32mp1-rtc.
Difference is that stm32mp25 soc implements a triple protection on RTC
registers:
- Secure bit based protection
- Privileged context based protection
- Compartment ID filtering based protection
This driver will now check theses configurations before probing to avoid
exceptions and fake reads on register.
