[PATCH v2 0/3] Introduce STM32MP1 RTC

[Amelie Delaunay]

This series introduces STM32MP1 RTC.
On STM32MP1:
- two clocks are needed, plck and rtc_ck;
- to wakeup the system, a wakeup alarm interrupt is needed;
- some registers or bits have moved, but the operation is the same;
- the Backup Domain Protection (DBP) is not managed by RTC driver.

---
Changes in v2:
* One compatible per line in bindings file
* Remove unnecessary comment under rtc_ck as this clock is required for all
* Remove interrupts-extended and add stm32mp1 rtc alarm wakeup interrupt in
  interrupts property description
