430aa33a30 dt-bindings: rtc: qcom-pm8xxx: add nvmem-cell offset
On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which a
driver can take into account.

Add an 'offset' nvmem cell which can be used to store a 32-bit offset
from the Unix epoch so that the RTC time can be updated on such
platforms.

The RTC can be used as a wakeup source on at least some platforms so
allow it to be described as such.
