Add missing utc_offset call for the local time RTC case

No clue of the talking to the hardware part is right, but I believe the time handling is now correct.

171–173	Isn't `ct.min != oldct.min` the only check that matters here?

jrtc27 added inline comments.Aug 18 2022, 9:29 PM

sys/dev/dialog/da9063/da9063_rtc.c
171–173	In practice yes, but technically you could, say, get preempted for an {hour,day,month,year} (which in reality would only ever happen if using a debugger and you got unlucky) so {min, hour,day,mon,year} would fully wrap around, and it felt wrong to be lazy.

Renamed da9063 to da9063_pmic
