nrf: rtc: persist rtc offset across reboots
Store the RTC value in the .uninitialized section, but make sure to
flank it with some known values. That way we can determine if the RTC
value has been initialized, or if it's random uninitialized garbage.
As part of this, add a `common_hal_rtc_init()` routine to determine if
the value is correct, or reset it to 0 if it is not valid.
