Commit Message

Chen, Yu C June 8, 2020, 7:41 a.m. UTC
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.
