Subject: drivers/rtc/rtc-hym8563.c: set uie_unsupported
The alarm of the hym8563 only supports a minute accuracy, while the uie
wants an alarm one second in the future. Therefore things like the
select() syscall will fail with a timeout, because the next alarm will
happen in a worst case of 60 seconds.
