Currently we're forced to have system time in the UTC timezone as
hardware clock, mainly because kernel expects in rtc_hctosys(), that RTC
time is held in UTC timezone.
With this patch one can now have local system time for example in CEST
timezone and RTC time still in UTC with boolean config option `rtc_utc`.
