tracing: use macros to denote usec and nsec per second
Impact: cleanup Use USEC_PER_SEC and NSEC_PER_SEC instead of 1000000 and 1000000000. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> LKML-Reference: <49CC7870.9000309@cn.fujitsu.com> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
