Series rtc: pm8xxx: add support for setting time using nvmem | expand

Commit Message

Johan Hovold Feb. 2, 2023, 3:54 p.m. UTC 
The PMIC RTC registers are 32-bit so explicitly use u32 rather than
unsigned long for timestamps to reflect the hardware.

This will also help avoid unintentional range extensions when adding
support for managing an external offset.
