[PATCH v3 2/5] dt-bindings: rtc: qcom-pm8xxx: document qcom,no-alarm flag

[Jonathan Marek]

Qualcomm x1e80100 firmware sets the ownership of the RTC alarm to ADSP.
Thus writing to RTC alarm registers and receiving alarm interrupts is not
possible.

Add a qcom,no-alarm flag to support RTC on this platform.
