clocksource: Convert s[n]printf() to sysfs_emit()

Browse Source 
Per filesystems/sysfs.rst, show() should only use sysfs_emit() or
sysfs_emit_at() when formatting the value to be returned to user space.

coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().
