Currentlt some code flow of runtime usage count changes is not covered by 
the tracepoints. Add corresponding tracepoints to monitor all the usage_count
changes.

In order to track all the runtime usage count change, move the code
related to runtime usage count change from pm_runtime.h to runtime.c,
so that in runtime.c we can leverage trace event to do the tracking.
Meanwhile export pm_runtime_get_noresume() and pm_runtime_put_noidle()
so the module can use them.

No functional change.

Commit d229290689ae ("PM-runtime: add tracepoints for usage_count changes")
has added some tracepoints to monitor the change of runtime usage, and
there is something to improve:
1. There are some places that adjust the usage count have not
   been traced yet. For example, pm_runtime_get_noresume() and
   pm_runtime_put_noidle()
2. The change of the usage count will not be tracked if decreased
   from 1 to 0.

This patch address above issues by tracking the usage count whenever
it has been modified. And these changes has helped track down the
e1000e runtime issue.

IIRC, rpm_idle() has a tracepoint already.

This actually changes logic, so it doesn't match the patch description.

Yes, this is what I concerned previously. If someone
want to track the change of usage_count, then he might
have to enable both trace rpm_usage and rpm_idle so
as to track the moment when the counter drops from 1 to
0. It might be more consistent if we only enable
trace rpm_usage to track the whole process.

This patch intends to adjust the logic to be consistent with
the change of usage_counter, that is to say, only after the
counter has been possibly modified, we record it. In current
logic above, it tracks the usage count where the latter does
not change.

I see now what you intended. I think it would be nice to put the idea
(that all usage changes be shown using rpm_usage even if included in
other trace points) into the commit message. Otherwise, looks ok.
