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.

Since v1:
 - Replace "anyOf: const:" by "enum:"
