[U-Boot] [PATCH v1 2/5] rtc: ds1374: remove redundant code in rtc_reset

As of commit 1a1fa2406689 ("rtc: Set valid date after reset") the
command "date reset" will set the date/time to 2000-01-01 0:00:00 after
calling rtc_reset(). This means that the ds1374 implementation of
rtc_reset() doesn't need to call rtc_set().
