rtc: ds1307: rx8130: Fix alarm handling
[ Upstream commit 3f929cad943380370b6db31fcb7a38d898d91089 ]
When the EXTENSION.WADA bit is set, register 0x19 contains a bitmap of
week days, not a day of month. As Linux only handles a single alarm
without repetition using day of month is more flexible, so clear this
bit. (Otherwise a value depending on time.tm_wday would have to be
written to register 0x19.)
Also optimize setting the AIE bit to use a single register write instead
of a bulk write of three registers.
