rtc: max77663: Set Alarm wday to its reset value
The wday is configured only when disabled alarm.
When enable alarm, set it to its default reset value 0x01,
and not enable it, to prevent an error happened when re-read the
alarm value into the virtualized generic layer at boot up in
reading alarm setting of RTC.
