Subject: [PATCH 21/24] arm64: dts: qcom: sc8280xp-pmics: add pmk8280 rtc

The PMK8280 has an RTC which can also be used as a wakeup source.

Note that the RTC can not be disabled and updating the time is not
permitted either. Instead an offset can be stored in some other machine-
specific non-volatile memory which a driver can take into account.
