rtc: ds1685: use sysfs_emit() instead of sprintf()
Use sysfs_emit() instead of sprintf() in sysfs show callbacks
(ds1685_rtc_sysfs_battery_show, ds1685_rtc_sysfs_auxbatt_show and
ds1685_rtc_sysfs_serial_show) to conform to the recommended sysfs
attribute formatting guidelines in
Documentation/filesystems/sysfs.rst.
