rtc/nuc900: fix checking of args during time-setting
When a user application wants to set the rtc time, the RTC subsystem takes
advantage of 'rtc_valid_tm(tm)' to check 'rtc_time *tm' value validity, it
make sure the 'tm->tm_year' is larger than 70,so if '70< tm_year < 100',
the '(settm->tm_year - 100)' will be negative. ' Setting the negative
value to hardware register will be invalid, so I add the 'if' condition to
make sure set a valid value to register.
