[PATCH 10/12] rtc: isl1208: use sysfs_emit() instead of sprintf()

[alexandre.belloni@bootlin.com]

From: Alexandre Belloni <alexandre.belloni@bootlin.com>

Use sysfs_emit() instead of sprintf() in sysfs show callbacks
(timestamp0_show, isl1208_sysfs_show_atrim, isl1208_sysfs_show_dtrim
and isl1208_sysfs_show_usr) to conform to the recommended sysfs
attribute formatting guidelines in
Documentation/filesystems/sysfs.rst.
