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.
