coccicheck complains about the use of snprintf() in sysfs show functions.
Fix the following coccicheck warning:
drivers/counter/stm32-lptimer-cnt.c:265:8-16: WARNING: use scnprintf or sprintf.
drivers/counter/stm32-lptimer-cnt.c:176:8-16: WARNING: use scnprintf or sprintf.
Use sysfs_emit instead of scnprintf or sprintf makes more sense.
